Alpine is considering switching Jack Doohan with Franco Colapinto in time for F1's next race at Imola
Doohan's place in F1 has been under constant scrutiny since Alpine signed Argentinian star Colapinto
has been underwhelming in the six races of his rookie season so far
While he has shown flashes of encouraging qualifying pace, crashes in Australia and Japan raised alarm within the team -- his first-corner tangle with Liam Lawson during Sunday's Miami Grand Prix was terribly timed in the context of his F1 future
Sources have told ESPN a plan to put Colapinto in the car for Imola gathered pace during the weekend in Miami
but the cogs appear to have been turning behind the scenes for a while
CEO of the Argentina energy company and Colapinto backer YPF
was caught off-mic during a break in an interview saying he would be in the car for the Italy race
Doing so now would allow Colapinto three consecutive weekends of racing
with Imola's contest followed by races in Monaco and Spain
Nothing has been confirmed yet and Alpine is expected to use the off week between Miami and Imola to decide the next course of action

Colapinto became an overnight superstar in his home country after his unexpected elevation to a Williams race seat last summer as Logan Sargeant's replacement
Colapinto joined Alpine on a loan deal at the start of this year -- Williams boss James Vowles strongly hinted at the start of the year the deal was signed off because it would eventually lead to race experience
Alpine boss Ollie Oakes had downplayed the switch on Friday ahead of the Miami race: "As it is today
Jack is our driver along with Pierre," he said
he also said: "We've been pretty open as a team that that's just noise
But it's natural that there's always speculation there."
Oakes cancelled his planned Sunday evening media session
with the official reason being a change in travel plans
That is not uncommon for team bosses after races featuring delays due to weather or red flags
but Miami's race had gone exactly to schedule despite pre-race fears over rain and thunderstorms
ESPN understands Doohan would still remain with the team in some capacity should the Colapinto swap take place

Jack Doohan is expected to be replaced for the next Formula 1 race at Imola after Alpine informed the rookie of its intention to make an immediate change
Alpine promoted its junior driver to a race seat for 2025 after losing out on Carlos Sainz to Williams
But Doohan’s seat seemed at risk before he had even raced in F1 as Alpine executive advisor Flavio Briatore explored the prospect of signing Franco Colapinto late last year
Alpine was in talks to bring in 2024 Williams stand-in Colapinto for this season as a reserve and potential race driver even as Doohan made his debut in place of Esteban Ocon in the 2024 season finale
Then Colapinto officially joined Alpine in January this year
magnifying the pressure on Doohan in the build-up to his rookie season
Though he has shown strong underlying pace at times and even surprised some at Alpine with how fast he was early in the season
Doohan has also had a run of incidents and is without a point after six races
He retired from Sunday’s Miami Grand Prix following a first-corner clash with Liam Lawson - after outqualifying team-mate Pierre Gasly for the first time in a grand prix qualifying
Doohan’s poor results are partly owed to Alpine’s own unexpectedly tricky start to the year after a good pre-season but he has often struggled compared to Gasly
While this is broadly in line with what might be expected of a rookie
Doohan has not been afforded the same time as others
GPs: Gasly 5 - Doohan 1Sprints: Gasly 1 - Doohan 1Average gap: Gasly 0.367s ahead
The Race understands Doohan was informed before leaving the track in Miami on Sunday night that Alpine intended to make a change
Colapinto is in line to replace Doohan from the next race at Imola
is also an option for its driver line-up this season
will remain part of Alpine's overall driver roster as it stands
Alpine is yet to comment on Doohan’s situation or its driver intentions

Alpine is considering switching Jack Doohan with reserve driver Franco Colapinto ahead of Formula 1's next race in Imola
Doohan's disappointing run of results and incidents have moved Alpine's management to seriously consider whether it should make a driver change immediately rather than hand the Australian rookie more time to make the seat his own
Neither driver was wholly to blame for what was deemed a racing incident
but it added to the growing list of on-track issues – including a huge crash in Suzuka practice – which hampered Doohan's campaign
The French team has a 2025 car with potential
as evidenced by Gasly's excellent seventh place at the Bahrain Grand Prix
But other than a Miami sprint race point for Gasly due to three time penalties for his rivals
this was Alpine's only points finish this year
In contrast, a ferocious midfield battle saw Williams lead the charge in fifth followed by Haas. Alpine is a disappointing ninth in the standings ahead of only Sauber
which may well force the Enstone squad to reconsider its options
Ever since 2024 Williams reserve Colapinto was signed by Alpine over the off-season, rumours swirled over Doohan's longevity with the Enstone squad
noise that Alpine admitted was partly of its own making
That pressure has only ramped up in recent weeks
with the CEO of Argentinian energy giant YPF Horacio Marin caught saying Colapinto would be in the car "in Imola" after a TV interview
later clarifying it was only wishful thinking on his behalf
Alpine team principal Oliver Oakes said: "I think it was a sponsor from Argentina off-camera giving his view on Franco
I’m sure there’s a lot of people in Argentina who’d like him in the car this Sunday
We’ve been pretty open as a team that that’s just noise
But it’s natural that there’s always speculation there
When pressed for a black and white answer on whether Doohan will remain in the car in two weeks in Imola
Oakes said Doohan was the team's driver "as it is today," leaving wiggle room for interpretation before adding the team is "always evaluating" its line-up
making a decision before Imola would make sense as the Emilia Romagna Grand Prix on 18 May forms the first race in a triple-header that includes Monaco and Barcelona
But Motorsport.com understands that timing is not a factor in Alpine's decision
In any case, Colapinto is well prepared to step in at short notice as part of his reserve duties with a mixture of simulation work and private testing, and it is worth pointing out that the Argentinian made his F1 debut last year in the middle of a Zandvoort-Monza double-header
Colapinto caused an immediate impact on his nine-race Williams cameo replacing Logan Sargeant
which led to a brief spell of interest from Red Bull
But the Argentinian's inexperience also showed in violent crashes in Las Vegas and Brazil
which put Red Bull off his scent before Alpine swooped in over the off-season to add the 21-year-old to its roster of reserve drivers
Alpine advisor Flavio Briatore, who runs the team alongside Oakes, is reported to be keen on giving Colapinto a chance sooner rather than later
The Argentinian also enjoys considerable backing from his supportive home country
with sponsor Mercado Libre already following him from Williams to Alpine

Alpine look set to replace Jack Doohan with Franco Colapinto for the next round of the F1 season
Alpine looks increasingly likely to switch Franco Colapinto in for Jack Doohan at the Emilia Romagna Grand Prix in two weeks' time
RacingNews365 understands the decision is close to being finalised after the Australian suffered another ultimately disappointing weekend at the Miami Grand Prix
It comes less than a week after a sponsor of Colapinto's suggested he would "debut" for Team Enstone at Imola in a hot mic gaffe that was subsequently walked back
Doohan's round at the Miami International Autodrome was a microcosm of the 22-year-old's season thus far
out-qualifying team-mate Pierre Gasly for the first time to start the race from P14
contact with Liam Lawson in the first corner consigned him to a second first lap retirement in six events
after his first lap crash at his home grand prix in Melbourne
picking up penalties in both the sprint and grand prix at the Shanghai International Circuit
was his heavy shunt during practice for the Japanese Grand Prix after leaving DRS engaged heading into the high-speed first corner
a mistake Alpine publicly placed at Doohan's feet
On Friday evening in Florida, he could not stifle his frustration after Alpine contributed to him getting knocked out of SQ1, lamenting the course of events as "not acceptable" and a "joke" over team radio
He is one of only four drivers not to score a point so far this year
As brutal as a driver change just six rounds into the season is
The move falls in life with the persistently-denied rumour Doohan had only five or six rounds to impress at Alpine
There has also been rampant speculation about a swap between the two drivers since before the campaign got underway - and before Colapinto had even signed for Alpine from Williams
it had appeared Doohan would be given until the summer to prove himself
Team principal Oli Oakes did not conduct a media session on Sunday evening in Miami as he usually does
Do you think Alpine should switch Colapinto in for Doohan ahead of the next round

Alpine boss addresses slip-up suggestion a driver change is imminent
Jack Doohan A slip of the tongue from a sponsor of Franco Colapinto’s has forced Alpine to swiftly address the red-hot driver rumour
Jack Doohan had not even driven the first grand prix of his rookie season
when suggestions started that he could be dropped from his race seat
Alpine signed Colapinto
Now the suggestion that Doohan’s days in the car are numbered have amplified due to a remark
was overheard speaking because his microphone was still live
even though he was no longer recording a TV segment
the context being when Colapinto would return to the F1 grid
The F1 Emilia-Romagna Grand Prix is May 19 meaning
that Doohan’s time in the Alpine is drawing to a close already
"I’m sure there’s a lot of people in Argentina who’d like him in the car this Sunday
But it’s natural that there’s always speculation there."
Oakes was asked to confirm if Doohan would drive at Imola later this month

It appears we have our second in-season Formula 1 driver axing in 2025, with Alpine set to replace Jack Doohan with Franco Colapinto from the next race at Imola
A driver change in season is always a sad development and very rarely anyone’s intention.
It reflects something not going as hoped or planned
there is a particularly cruel aspect in that someone’s dream is over
and what they’ve worked incredibly hard to earn is taken away
What is earned must keep being earned and F1 drivers are subject to pretty excruciating
was a function of the team’s tendency for upheaval.
and his extensive testing programme were all put in place well before the current Alpine team leadership were around.
He isn’t ‘their’ driver. Never really was
And Oliver Oakes didn’t even join Alpine himself until the die was cast
as Alpine had missed out on Carlos Sainz - with Doohan left as the path of least resistance.
while Oakes was keen to back Doohan as much as possible
because that was in the team’s best interest
he and Briatore were inevitably going to want to make their own driver choices at some point.
Now that’s finally happening at Doohan’s expense
on a harsh timeline for any team except maybe Red Bull
To select a driver and only run them for the first six events of a season (and one at the back end of the previous year) without being forced into the situation always reflects badly on a team's decision-making processes
But while Doohan deserves enormous sympathy for the sudden interruption
but at the top level you have to seize whatever opportunity you get with both hands and make the most of it
Doohan has failed to do that and make himself undroppable
which realistically was what he needed to do in the early races of 2025 to avoid this fate
You can argue that he was being set up to fail
but in F1 you are always vulnerable if you don't prove yourself to be a superstar driver and Doohan fell short of that.
it is a shame given he did show plenty of signs of good underlying speed
notably in outqualifying team-mate Pierre Gasly in main qualifying last weekend
There's no doubt he had the ability to become a regular points scorer
certainly at the tracks where the weaknesses of the Alpine package didn't make it impossible
and with more time there's no doubt he'd have had some strong weekends
Elite sport can be cruel and Doohan has good reason to feel hard done by
but the reality is that he didn't do enough to stave off his fate
The team certainly didn't put him in a position to deliver his best and Doohan himself knew full well he was walking a tightrope
he could have done more even with this narrow window of opportunity
We didn't see the best of Doohan this year
He will rue the fact that he only sporadically showed the very real pace that
Doohan hasn’t made a great fist of trying to seize his chance at the start of this year
The team undermined its rookie driver before the season had even started by dangling Colapinto over his head
it’ll be able to point to Doohan’s patchy handful of weekends as justification for the switch.
Will Alpine also accept that it didn’t give Doohan the best environment to get the job done due to the circumstances it created around him?
I’ve seen his struggles to look comfortable in F1 compared to the other rookies that have got off to good starts in 2025
but none of those came into this year fearing that after a handful of races they could be gone
So it’s not an entirely fair comparison.
The only surprise in this whole affair was the brief moment where it looked like the team had changed its mind and was going to give Doohan at least half a season. What happened with that?
it’s utterly plausible that someone changed their mind based on nothing of substance
Or perhaps it was a way to smoke out some more commercial support from South America
or speed up any incoming payments from existing arrangements…
None of the above is a reflection on Colapinto’s worthiness for an F1 seat
He should get off to a better start than Doohan did
let’s hope he’s given more time to turn it around.
Doohan definitely did not make an ironclad case that he was Alpine's best possible version for the long term
but there was also clearly no priority given to making this work
He was put in an unreasonable situation and couldn't beat the odds
I'm not naive enough to pretend this is a novel way of going about business for F1
it is probably no coincidence Alpine team boss Oakes has spent much of this year sounding like a punchier
jokier Christian Horner - and it's not like most F1 teams wouldn't discard both of their drivers in a heartbeat if they felt doing so could improve the team situation
very funny when you remember the whole Oscar Piastri thing
all that hand-wringing about driver loyalty
all those quotes from then-Alpine chief Laurent Rossi about how now the Alpine Academy was suddenly maybe not worth it anymore because drivers and their management lacked integrity
Different people are in charge now at Alpine
they certainly do not have to answer for Rossi's words
It's a wider top-level motorsport thing anyway (yes
I'm thinking about the whole Alex Palou/McLaren saga)
No F1 driver should ever be faulted if they leave a team
even if everyone's saying they owe that team a lot
They can never-ever hesitate - because team bosses certainly will not
For all that Jack Doohan’s likely early exit from Alpine may seem unfair
considering some strong potential he has shown
we have to remember that Formula 1 is not a charity
And one of the harsh realities about life as a F1 driver is that when opportunity comes knocking
Just look at how Ollie Bearman’s destiny changed when he pulled off that sublime performance in Saudi Arabia last year
or even how Colapinto wasted no time in getting up to speed with Williams in Monza and Baku last year
Doohan’s run of seven races offered plenty of opportunities for him to prove to his Alpine bosses that he was the right man to lead them on
the biggest ace up his sleeve was incumbency
teams do not keep drivers because of their potential tomorrow – they want to see what you deliver today.
a bunch of penalties and that Japanese GP crash (even though it emerged afterwards it was not 100% his fault he kept the DRS open) are the opposite of what Alpine needed
which was strong finishing positions and some points on the board
There is no excuse that rookies need time to get up to speed now – just look at Isack Hadjar and how Kimi Antonelli put his Mercedes on pole position in the sprint race last weekend.
even with the competitive situation of Alpine not being brilliant
was make progress and ram home some finishes that showed he was moving onwards and upwards
Some of these team principals need to take a good look at themselves and realise they are actually playing around with someone’s careers if not lives
They don’t seem to take any responsibility for these rash decisions
Liam Lawson was a typical example at Red Bull
and now Doohan at Alpine - the management of both these teams made decisions to give these drivers a shot at the big time
so they should see that out and give them a fair crack of the whip
it’s a bit 'how long is a piece of string?'
the drivers have had the chop when at least
50% of the root cause of their failures were actually down to the teams
I think they should stand by their commitments and give these guys a chance until they get a minimum of three clean race weekends and then make a judgment and not a spur-of-the-moment decision after a bad weekend
As far as the Alpine decision is concerned
and its comments over the weekend it shows that Oliver Oakes
Alpine’s ‘team principal’ is simply a puppet
with Flavio Briatore pulling the strings behind the scenes.
do I think Lawson or Doohan are or were going to be the next Max Verstappen
Probably not - but then is there another one on the horizon
probably Piastri is in line for that accolade
but is Colapinto a step forward from Doohan
If he can repeat his early performance when he replaced Logan Sargeant
But if he performs like he did at the end of his time in the Williams
another Formula 1 team has fallen victim to its own decisions
The moment Alpine signed Colapinto as a reserve driver
I know F1 is a brutal business - but before Doohan had even started the season
he was already under intense public pressure after the team he had been nothing but loyal to decided to put an alternative driver as a potential replacement in the shop window for everyone to see
Has Doohan seized the opportunity given to him
but Alpine certainly haven’t provided him with the environment to thrive either
this is the same team that let current championship leader Piastri slip through their fingers into the welcoming arms of McLaren - so should we really be that surprised
Andres Marin and Tad McCrea made the first ascent of the south face of Mount Providence in the Alaska Range
Their new 1,000-metre route is called Journey Through the Castle of Providence and graded WI4 M5 5.10 with steep snow
The first ascent team first spotted the line in 2024 from the Thunder Glacier
“After a stretch of inclement weather, we were lucky to catch a narrow window and flew into the range,” Pfaff told Planet Mountain
“Conditions on the face were better than we could have hoped
The lower half climbed through steep snowfields
eventually leading to a rock headwall lined with huecos and chicken heads
corniced ridge finally brought us to the seldom touched summit.”
There are several reports of new routes on Providence in the American Alpine Journal, read one from 2017 here and 2005 here.

And was his start to 2025 sufficiently disappointing that he deserves to be replaced after just six rounds
Our international panel of writers have their say
Let’s say that Doohan has been under such pressure since the beginning of his journey as a full-time driver for Alpine — pressure that has been largely fuelled by the (sometimes not so) ambiguous statements from his bosses — that one could argue whether Alpine is right to consider replacing him is almost irrelevant
The question always seemed less about "if" and more about "when"
Photo by: James Sutton / Motorsport Images
Doohan's days seemed numbered from the start
and the dice appear to have been loaded in favour of Colapinto
The Australian couldn’t have been unaware of this
he didn’t do himself any favours by rarely matching his team-mate’s performance on track and by getting involved in costly incidents — the most obvious being his big and silly crash at Suzuka
while it's true that Doohan's seat never seemed secure beyond a few GPs anyway
and certainly not as much as Colapinto did during his short stint at Williams last year
(The Argentine also had some big crashes but at least he scored points.) In short
this is not a move that presents any major sporting risks and could offer some attractive financial opportunities
It’s not a question of whether Alpine is right or not
Doohan hasn't really been there since the season started less than two months ago in Australia
and six rounds in F1 these days is enough to know if a driver can deliver or not
Let’s look at the facts. There's a narrative — a word much used in the paddock last weekend in Miami — that Doohan has shown flashes of raw pace on one lap. But Pierre Gasly has outqualified him 6–2 so far — sprints included — and the average gap between the two is 0.367 seconds
Gasly has finished ahead of Doohan in five out of six races
If you’re wondering in which grand prix the Aussie beat the Frenchman — well
that was when Gasly was disqualified for a technical infraction in Shanghai after finishing 11th
Alpine has a driver in Colapinto who has already proved he can swim when thrown in at the deep end
as was evident when he started his racing tenure with Williams
He scored points in Baku — with a Q3 appearance — in just his second race
on his way to completing his first five grands prix with an average finish of 10.6
Doohan’s so far — albeit in different machinery — is 15.6
You can really feel for Doohan if this is truly the end of his time with Alpine — his situation could probably have been different if Colapinto hadn’t been waiting on the sidelines
he got six races to prove himself — something not everyone got this season..
The story of Doohan and Flavio Briatore reminds me — an Austrian — very much of the story of Alexander Wurz and Flavio Briatore
Wurz was Formula 1’s next big thing — if only for a few months
when he refused to sign a management deal with Briatore and subsequently fell out of favour
Doohan is now learning the same lesson: that it’s difficult to sustain a Formula 1 career within a Briatore-led team unless you have Briatore’s full backing
One could argue about whether Doohan is a future world champion or not
But the fact that speculation about his replacement with Colapinto surfaced during the off-season — long before the first race had even taken place — hardly provides the kind of stable environment a young driver needs to unlock his full potential
Would Doohan perform better if his future weren’t constantly being called into question
Would his performances be strong enough to justify keeping Colapinto — with his talent and the financial incentives he brings — on the sidelines indefinitely
It’s a pity that Oliver Oakes didn’t seize the many opportunities he had to put an end to the rumours once and for all
A statement that includes "as of today" is not a statement
Just like you don’t give a compliment by saying
but…" That’s something Toto Wolff once taught me
I would have liked to see how good Doohan could have been if his team had given him full trust
Poor Jack was never really given a serious chance
I would personally like to see Doohan get more time, because I do believe in giving rookies enough seat time to settle — see Yuki Tsunoda — and by all accounts he is a good guy
they can be expected to perform at a high level immediately
That means not only showing flashes of pace
trouble-free performances that teams can rely on to come out on top in the closest midfield battle in F1 history
it hasn’t happened yet for Doohan — which is a shame
The question is now: Will that consistency come in good time or not
It feels obvious that it’s a question of when
why go through the trouble of prying him loose from Williams — which also assumed he would get promoted eventually
If the team feels Doohan’s adaptation is going to take too much invaluable time
then you can see why it would slot in a ready-made replacement ahead of a busy European run-in rather than delay the inevitable
but I do think this is about performance first
There aren’t many guys in the paddock as humble
Losing a job he loves and was so desperate to get is not something you’d wish on anyone
he must have been aware things may change quickly if he didn’t deliver
as a rookie he was put in a very difficult situation and asked to perform straight away
but the situation would’ve been a lot different had his path to F1 been more successful
And you can’t separate the two parts of a career
The ones who prove themselves to be excellent in junior categories tend to get more time and patience from their F1 bosses
they prove themselves a lot faster than those who didn’t really shine in previous championships
Doohan got as good a chance in F1 as he probably deserved — and it was
under enormous pressure — yet he still got that chance
Colapinto’s path to F1 wasn’t that straightforward either — yet
he did exactly what the F1 paddock values so much: he impressed
And that’s ultimately all there is to know…
has yet to score a point in six races this season and one at the end of 2024
The Race.com website said Alpine were evaluating Doohan’s position following another retirement at the Miami Grand Prix on Sunday
The driver has been dogged for months by questions about his future
with Alpine signing Argentine Franco Colapinto from Williams as a reserve before the start of the season
Colapinto raced nine times for Williams last year as replacement for dropped American Logan Sargeant and scored five points
with a best finish of eighth in Azerbaijan
lpine’s executive advisor Flavio Briatore

Alpine team boss Ollie Oakes cancelled his regular media session after Sunday’s race in which Doohan collided with New Zealander Liam Lawson’s Racing Bulls on the opening lap and retired
Jack is our driver along with Pierre (Gasly),” Oakes had said on Friday when asked to confirm Doohan would be in the car at Imola
Apart from Doohan’s lack of points and failure to finish higher than 14th
the latest rumour of an impending change were triggered by one of Colapinto’s Argentine sponsors suggesting in an unguarded television moment last month that it would happen for Imola
He later clarified it was only a personal opinion
“I’m sure there’s a lot of people in Argentina who’d like him in the car this Sunday,” said Oakes when asked about that on Friday
“We’ve been pretty open as a team that that’s just noise
But it’s natural that there’s always speculation there.”

The Argentine’s name routinely has been considered as a replacement for Doohan
who has struggled in six races during his rookie season
was caught off-microphone in a recent interview saying Colapinto would be in the car for the May 18 race in Italy
Speculation has been rampant given Doohan’s poor start
including a first-lap crash at the Australian Grand Prix on March 16 and four penalty points at the Chinese Grand Prix a week later
The 22-year-old Australian also crashed in the second free practice session ahead of the April 6 Japanese Grand Prix
Doohan, however, kept his spirits up after an opening-lap incident with Liam Lawson at the Miami Grand Prix
“We just have to look into it because it didn’t end well for me and I don’t think it helped him out as well. We’ve just got to keep our heads up. Looking forward to Imola now,” Doohan concluded. (Reuters)
Alpine is evaluating Jack Doohan’s position and considering whether a driver change is needed as soon as the next Formula 1 race at Imola.
Doohan’s Miami Grand Prix ended on lap one after contact at the first corner with Liam Lawson
who Doohan hit after braking early on the inside for Turn 1
then climbing over the kerb trying to avoid the Racing Bulls car.
It is the latest in a disappointing run of races at the start of Doohan’s rookie season
which had actually begun brightly in terms of underlying pace.
But it has also been filled with several incidents
He crashed out of the season opener in Australia on lap one in the wet
picked up penalties in the sprint race and grand prix in China
crashed heavily again in Friday practice in Japan
and has now been eliminated on the opening lap for the second time in six events.
That record makes for an early trend of not piecing together complete weekends or delivering on the potential he has shown
it was particularly unfortunate as it came in the first race that Doohan had outqualified team-mate Pierre Gasly
He is one of four drivers yet to score a point in 2025
Doohan’s place has been at risk since Alpine signed Franco Colapinto from Williams as a test and reserve driver for 2025
Alpine’s executive advisor Flavio Briatore is a big supporter of Colapinto and has been keen to try him in a race seat
but there has been division within Alpine on how best to proceed as the preference of others is to give Doohan time
Alpine signed Doohan to the race seat in August last year and after extensive speculation at the start of the season about the threat from Colapinto, it was agreed that Doohan should have until the summer to prove himself - with Briatore even expressing that sentiment
as of the end of the Miami Grand Prix weekend
The Race understands that a change could be made early in the season after all
potentially in time for the triple-header that begins at Imola in two weeks’ time.
Alpine said it would not comment on rumours
and team principal Oliver Oakes did not conduct a media session on Sunday evening in Miami
Earlier in the weekend in an FIA press conference he had slightly equivocated on Doohan's position by saying "as it is today
Doohan expects to begin preparations at Alpine’s Enstone headquarters for the upcoming races
“It was obviously good to get my first qualifying in front of my team-mate and feeling confident in the car,” Doohan said of his Miami weekend.
“These are the small little wins that we unfortunately have to take from this weekend - but we'll be carrying that into Imola
“We have some sim work to do on the car and some sim work to do for the upcoming few races
although I feel like I haven't really even done much driving.
“So I will be just shifting the focus straight to what's to come.”
Whether he gets that chance depends on whether Alpine’s stakeholders opt to remain patient
or give Colapinto a chance after all.
The young Argentine driver made a strong first impression when he joined Williams for a part-season last year and scored points despite his inexperience
although did then have a mix of crashes and more difficult race weekends.
He also attracted significant backing from Latin American companies and that has carried over to Alpine
which struck a partnership with Mercado Libre in February.
Argentina’s state-owned oil company YPF is a Colapinto backer and
while it does not have a direct deal with Alpine
is now a strategic partner of Eni - Alpine’s energy and fuel partner as of February this year.
YPF CEO Horacio Marin made headlines when he appeared to state Colapinto would be driving for Alpine at Imola while unaware he was still on air during an interview in Argentina - although he subsequently claimed he was only expressing his personal hope that would be the case
Oakes also responded to that earlier in the weekend during his FIA press conference appearances
"I think it was a sponsor from Argentina off-camera giving his view on Franco
"I’m sure there’s a lot of people in Argentina who’d like him in the car this Sunday.
"We’ve been pretty open as a team that that’s just noise.
Utah — Lone Peak Police have identified skeletal remains found in Lambert Park last Friday as Gabrielle Makenna Shull of Alpine
Investigators were able to confirm the identity through dental records
The remains were found in Lambert Park by a person who was riding on horseback through the park
is an area that's "largely undeveloped and used for biking
and foot traffic," the Lone Peak Police Department said
went missing from her home in January 2024
and while many searches were conducted in and around Lambert Park at the time
More time is needed for detectives to complete their investigation
Police shared their thoughts are with Gabrielle's family at this time
Gabrielle's family released a statement saying
"Gabbie’s sweet personality has been and will continue to be greatly missed
Our family is so grateful her remains were found
many people who helped in trying to find her.”
Doohan, the 22-year-old Australian, faced rumours of his seat being under threat before he had even sat in the cockpit, having signed an early deal with Alpine before the driver market fully developed last season, while Colapinto impressed at Williams.
With Alpine keen to assess Doohan’s qualities, they put him in the car in Abu Dhabi at the end of last season, as well as the six races of this campaign. He is yet to earn a point — one of only four drivers in that unwanted category — and has had several big crashes, including a first-corner incident

Alpine is considering making the Jack Doohan swap out for Franco Colapinto imminently
Reports indicate that Alpine has informed its Formula 1 rookie Jack Doohan that he will be dropped immediately in favour of Franco Colapinto
F1 heads to Imola in just under a fortnight’s time and it could well be that an Argentine lines up alongside Pierre Gasly in the Alpine squad
Multiple reports point towards Alpine considering dropping Doohan ahead of the Emilia Romagna Grand Prix
less than a week after the CEO of a Colapinto sponsor let slip off mic that the Argentine could be making his F1 return in Italy
and led to Alpine Team Principal Oliver Oakes being met with questions at the Miami GP
“I saw it, like everyone else,” Oakes told select media
“I’m sure there’s a lot of people in Argentina who’d like him in the car this Sunday.
“We’ve been pretty open as a team that that’s just noise.
“Jack needs to continue doing a good job
That speculation is down to rumours from the off-season circling Doohan’s future at Alpine
and Executive Advisor Flavio Briatore’s consistent admiration of Colapinto
Colapinto was signed over from Williams to become Alpine reserve
his management team and James Vowles seeing it as the best opportunity for him to secure an F1 race seat in 2025 or ‘26
after an accomplished nine-race stint alongside Alex Albon last year
Colapinto’s chance will come sooner rather than later with The Race revealing Doohan has been informed of his brutal fate
Doohan is one of four drivers yet to score a point in F1 so far this season and here lies the problem Alpine has potentially decided is worth rectifying with a swap
that he has decent pace and through qualifying sessions he’s built himself up to Gasly’s level
In Miami, Doohan out-qualified his team-mate for the first time to line up 14th at the Miami International Autodrome on Sunday
Doohan was pinched at the apex of Turn 1 and was forced to hop over the kerb
where he bounced into the path of Liam Lawson’s Racing Bulls
A Lap 1 DNF after a strong qualifying session was the latest in a series of errors that have plagued Doohan so far in 2025
A Lap 1 in the admittedly tricky Lap 1 conditions in Melbourne
former race winner Johnny Herbert claimed race pace is where Doohan could find himself in trouble
“He hasn’t blown away by Pierre at all,” he said
so the race is something that he’s got to harness all the energies
Because I think Flavio is very aware that other people probably are interested.”
Oakes confirmed Doohan was a part of Alpine’s line-up moving forward
“Jack is our driver along with Pierre
“today” appears to have been the operative word

Patrick Mahomes is in the building. The Kansas City Chiefs quarterback, who is an investor in Alpine Racing
arrived at Hard Rock Stadium ahead of the Miami Grand Prix
He and his wife Brittany strolled into the paddock Sunday afternoon and made a beeline for Alpine Racing’s hospitality suite.
The three-time Super Bowl champion was among a consortium of celebrity backers
including his team-mate Travis Kelce and golfer Rory McIlroy
who joined Otro Capital investment’s in the Enstone-based outfit in 2023
He looked laid-back in a striped Louis Vuitton matching set
He added a pair of statement blue sunglasses and adidas sneakers
while Brittany stunned in a beige corset and white pants.
The Texas Tech alum is no stranger to the F1 paddock. He's attended multiple races, including last year's Miami Grand Prix. He and Brittany spent time with Gasly and then-teammate Esteban Ocon
before celebrating at the swanky Carbone Beach party.
Patrick previously said he "jumped" at the opportunity to invest in the Oliver Oakes-helmed outfit. "I've always had a passion for all sports," he said in 2023
"The opportunity to lead an investor group with Travis in Alpine F1 alongside Otro Capital was one I couldn't pass up
It's an exciting time for the sport and this is an opportunity to bring our shared values to the world stage
I'm looking forward to being a part of its growth."

MIAMI -- Jack Doohan said he has felt "immune" from the pressure associated with the constant speculation over his future of Alpine
ahead of a Miami Grand Prix many felt he would not be participating in
Doohan's rookie season has been overshadowed by Alpine signing Argentinian driver Franco Colapinto on board as a reserve driver in early January
suggested Colapinto would have replaced Doohan by the Miami GP
although speculation of a swap has cooled over the first few weeks of the season
Doohan is racing this weekend as normal and it remains unclear whether Colapinto will move into the seat in the future
when there was the most noise," Doohan said during Thursday's media day about the external noise around him
But I think there was a new narrative each weekend
I knew what was irrelevant and what wasn't true
I never had that or felt that on the back of my mind
But I was more just focused on being as focused as I can in the car
rather than thinking about anything external
since this topic's been around for so long
"If it might have started just a couple of days before Melbourne
Doohan said Alpine advisor Flavio Briatore's straightforward approach to their conversations about the future have been helpful in keeping his fears at bay
"He's [someone] that I've looked up to for a very
"And I love him being brutal and very to the point where there's no BS
I prefer that much more than Chinese whispers."
He added: "Things were clear in what was happening
And things are always out there for a reason
So I think it was just keeping my head down and doing my job
the team is considering swapping out Jack Doohan for reserve driver Franco Colapinto as early as the upcoming Emilia Romangna Grand Prix in Imola
has already ignited a wave of fan reaction online—ranging from sarcastic disbelief to outright frustration
“Is anyone actually surprised?” one fan posted bluntly. Another wrote
We’ve known they’re gonna do it”—referencing the growing speculation and even leaked comments from sponsors suggesting Colapinto’s debut was imminent
Doohan, the 21-year-old Australian, has been widely seen as a promising prospect. Though Alpine’s performance has struggled overall, Doohan has shown resilience, racecraft, and consistency in difficult machinery. Fans were quick to come to his defense
“IMHO Doohan has shown in the lower formulae that he has pace
Franco Colapinto before the Las Vegas Grand Prix
Others took aim at what they perceive as deeper problems within Alpine—and f1’s talent pipeline altogether. Some pointed fingers at Red Bull, with one sarcastic post reading: “Red Bull has done irreversible damage to this sport.”
And of course, it wouldn’t be F1 Twitter without a bit of dark humor: “So they can have millions more in crash damages.”
While Colapinto is an exciting talent—Argentina’s brightest F1 hopeful in years—the way this potential switch has surfaced is raising concerns
Imola would mark Colapinto’s long-awaited debut in F1
but it may come at the cost of momentum and morale inside Alpine’s already unstable garage
fans are left to refresh feeds and fire off hot takes—while Doohan and Colapinto wait for clarity from the top

Pierre Gasly: "Overall
"At least we are leaving Miami with one point following the Sprint Race yesterday
We knew that today's race was going to be tricky after having had a couple of issues on the car which we tried to fix for today
I suppose we would have liked the rain to come during the race to give us a chance to fight but it did not come in the end
We need to do some analysis on the performance we had here as we have been faster in previous races
We have work to do between now and the next race in Imola."
Jack Doohan: "It was a tough end to the weekend for my side of the garage
We were starting from the middle of the pack which always creates a challenge coming into the first few corners
We were squeezed going into Turn 1 and with nowhere to go we had contact with [Liam] Lawson
The damage was too much to make it back to the pitlane safely and we ultimately had to retire the car
especially in managing the difficult weather conditions
and I have felt comfortable in the car across the weekend
Our focus now shifts toward the next few races
We have the week ahead to reset and work to prepare for the upcoming triple-header as we head into the start of the European season."
Team Principal: "We leave Miami disappointed where ultimately
we lacked performance to be competitive enough to fight for points
Although we did not come away from Miami empty-handed
Pierre was not happy with how the car felt in Qualifying and given his starting position we opted to make changes to his car and start from the pitlane
so in a conventional dry race we tried to make progress and pitted Pierre under the second VSC
Although we made up several positions ultimately it was only good enough for 13th
Jack's race unfortunately ended on the first lap after contact with Lawson at Turn 1
We have some time now between races to understand where we can improve and come back with some more performance for the European triple-header starting in Imola."

Jack Doohan has explained the pit lane "mess up" that left the Alpine driver frustrated over team radio
having missed out on progressing from SQ1 in Sprint Qualifying at the Miami Grand Prix
The Australian rookie was caught up in frantic pit lane traffic late on in the first segment of the session
which prevented him from leaving his garage properly
READ MORE: Antonelli storms to remarkable maiden pole ahead of Piastri and Norris during Sprint Qualifying in Miami
As a result Doohan was unable to make the turn out of the tight garage and subsequently lost time as he was pushed back into position
with a couple of other cars getting ahead in the pit lane queue
That traffic cost him the chance of making it to the start line for his last flying lap and Doohan cut a frustrated figure as he exited the session in 17th
that is not acceptable,” vented Doohan on team radio
with his engineer apologising for the situation that unfolded
you have to make sure he is ready or before me
I can’t turn out and then have to turn in because he is going to run into me and then you guys put me out of Q1
Speaking in the media pen after the session
Doohan explained the incident that led to his radio message: “It all comes down to the last flying lap and I think that the feeling was good
but I just ended up getting blocked on my way out the pit lane which was a mess up
“And then I wasn’t able to do another flying lap
That’s why they make the length of Quali that long
to do two laps and improve quite a lot on the second lap
I ended up being the last car out there and didn’t get a chance to do a second timed lap
Doohan exited Sprint Qualifying in the first segment
really messy – just trying a few things different from practice
there was a lot more time in the car for the second lap
Doohan expects a tough battle from the rear of the grid
while team mate Pierre Gasly will start from 13th position
“[I’ve] just [got to] try to move forward as much as possible
We have another shot at Quali tomorrow afternoon
just learn as much as we can from that for the main race and then focus on Quali,” Doohan added

Renault's long-time Formula 1 engine partner Mecachrome will remain involved in F1 in a new collaboration with the incoming Audi works team in 2026 after Alpine switches to Mercedes customer engines
The Mecachrome/Audi tie-up - which might not be Mecachrome's only new F1 deal - comes after another change to Alpine's motorsport engine arrangements with the decision to take its World Endurance Championship engine programme away from Mecachrome and move it fully in-house to the Viry-Châtillon Alpine motorsport base once the end of the F1 programme creates capacity
Mecachrome is best known among F1 fans for Williams and Benetton running engines bearing its name in the 1998 season
when Renault withdrew factory support but a deal was struck for Mecachrome to continue maintaining and supplying the engines to the former Renault teams
The firm has been involved in Renault's motorsport engine programmes for over 40 years
It currently manufactures some of the parts
assembles and tests Alpine's F1 engine blocks
It has quickly bounced back from the double blow of Alpine stopping its F1 engine programme and bringing the WEC engine work in-house by signing a new agreement with Audi
you are bound to be familiar with this French company
whose motorsport division is based in Aubigny-sur-Nère
with its recognised DNA in automotive sport and F1
has become a world leader in high-precision mechanics
Specialising in the machining of mechanical parts and high-precision assemblies
the group has the capacity for sheet metal working and boiler making
and assembly of larger assemblies (batches)
Mecachrome is present in the aeronautical (aerostructure
Its industrial potential and cutting-edge technologies
such as nanomechanics and HVOF thermal spraying
have enabled the group to forge an international reputation with its customers
The company employs more than 5000 people and has a global turnover of around €600million
its motorsport activities are mainly based at Aubigny-sur-Nère
F2 and F3 (with engines designed entirely in-house)
The automotive premium & motorsport department accounts for more than 18% of the company's total turnover
Mecachrome's teams have manufactured more than 7500 engines
in addition to being behind the V6 turbo engine for the Alpine A424 hypercar
Mecachrome was also the engine manufacturer for Ginetta in 2019
Mecachrome collaborated with Renault for over 40 years and contributed to 12 world championship titles in F1
though its own name only appeared on an entry list in 1998 - with even that ex-works Renault engine supply deal being rebranded for 1999 when Flavio Briatore and Bruno Michel's Supertec company took on the distribution of the Mecachrome engines that were by then being used by BAR too.
when it was announced last September that Renault was stopping production of its F1 engines
But it had to take another blow recently when it learned that Renault was bringing all its Endurance activities back in-house to its Viry-Châtillon centre
"These are decisions that have deeply affected our staff who worked in this sector and who were committed to motorsport," said Mecachrome CEO Christian Cornille
"This is the second piece of bad news we had to break to them a few days ago when we told them that we had not been able to keep this activity within Mecachrome
as Alpine had decided to take back the endurance business."
Alpine has confirmed to The Race that Viry will resume assembly and operation of the A424 WEC engines after the 2025 Le Mans 24 Hours (14-15 June)
once most of the F1 activities have been completed and there is availability at Viry
as Alpine has never hidden its desire to maintain a competition activity in Viry-Châtillon even after its F1 team moves to Mercedes engines
Alpine will continue to work with Mecachrome on its WEC programme
When it came to finding an engine to power its A424 WEC car
"The choice was made following a call for tenders," explained Alpine Motorsport vice president Bruno Famin in August 2023
"We consulted several engine manufacturers and finally opted for Mecachrome
The engine was modified to adapt to the constraints of endurance racing
although everyone still remembers last year's double retirement from the Le Mans 24 Hours before nightfall
which is said to have contributed to the good results achieved by the A424 at the end of last season
despite encouraging reliability in the last four races
Alpine has decided to use one of the five Evo Jokers available to manufacturers between 2021 and 2027 to modify its turbo
Frédéric Makowiecki and Jules Gounon finished third in the Imola 6 Hours
But to be sure that the work done has paid off
we will really have to wait for Le Mans next month
the V6 turbo in this car will now be assembled in Viry-Châtillon
at the Hypertech Alpine facility where the F1 engines were designed
The site transformation involved reallocating resources and competencies currently assigned to the F1 engine
Various activities are grouped together there: its in-development 'Future Alpine Supercar'
R&D on cells and new battery chemistries
research into new electric motor technologies
F1 monitoring unit to master technical developments in this industry
and the development of engineering services for other companies
But Mecachrome's expertise is well known in the industry
and it would have been surprising if other manufacturers had not taken advantage of the end of this idyll with Alpine/Renault to secure its services
we couldn't work with other teams because we were bound by an exclusive contract with Alpine," Cornille explained
"As soon as we were released from our obligations
which we will be supporting in the manufacture of a number of parts."
and the collaboration has obviously already begun
there is no question of assembling the engines; that's a task entrusted to Audi Formula Racing GmbH in Neuburg
in a specially adapted centre equipped with 22 state-of-the-art test benches
we manufactured parts and assembled engines," Cornille added
we manufacture parts but do not assemble engines
this allows us to minimise the social impact on our site in Aubigny."
But it also allows the company to remain involved in F1
especially as Cornille says he is in "advanced discussions" with another currently unnamed F1 team
There will be a late change to the grid for the Miami Grand Prix
Pierre Gasly is to start the Miami Grand Prix from the pit-lane following his Alpine team breaking parc ferme ahead of the race
Gasly was due to start in 18th place following being out-qualified by team-mate Jack Doohan for the first time in a grand prix
Alpine has elected to make set-up changes to Gasly's car
It means Lance Stroll and Ollie Bearman both shuffle forward one place to 18th and 19th

The new Vertex Alpine is a running shoe that actually climbs well
It’s been a long time since I’ve worn an actual “approach shoe” to a crag
Whether I’m hiking quickly along a dirt trail or boulder-hopping through talus
I find the average approach shoe to be overbuilt
I wear a lightweight trail runner to the cliff instead
a runner’s sole is rockered and heavily cushioned
known to have incredible durability nor climbing performance
Arc’teryx’s Vertex Alpine is an approach-runner hybrid, similar in design to Scarpa’s Rapid—but with more of a climber’s bent
The Vertex’s rockered sole propelled me across long Cascadian approaches last summer and its Vibram XS Flash 2 outsole rubber let me smear confidently through Red Rock canyons and Squamish chimneys
It has a drop of 8 millimeters (18mm heel; 10mm forefoot) which both cushioned my stride while pounding down the Stawamus Chief’s walk-off descent
and kept me close to earth while soloing fifth-class approaches
The Vertex is a true “climber’s running shoe” because
A stiff Thermoplastic Polyurethane (TPU) shank and the outsole’s lug-free “climbing zone” toe provides decent edging support on terrain up to 5.10-
And unlike flimsy mesh shoes like the Rapid
the Vertex’s upper is made of burly Matryx fabric—a breathable product found in hard-wearing items like harnesses and soccer cleats
this fabric lets the Vertex jam the occasional hand and fist crack without tearing
cushioned platform—have all conspired to make the Vertex my new quiver of one summer-alpine shoe
While testing in Washington Pass last summer
and ball-bearing scree for two hours to reach the base of the South Early Winters Spire
I left the Vertex on for Southern Man’s (5.11d; 900ft) first two pitches
then swapped into rock shoes as August’s blistering sun burned overhead
but we salvaged the day with comfortable feet while soloing the mountain’s South Arete (5.5) in the Vertex
That autumn I packed light on a 10-day climbing trip to Las Vegas, bringing just the Vertex, the TC Pro, and Qubit for all my footwear needs
The Vertex delivered in all areas you’d expect: I went for long runs across the limestone escarpment of Mt
I scrambled through cavernous sandstone canyons in Red Rock
and I climbed some low fifth-class terrain
But I also somehow lucked into a spot on the guest list at the Marquee Nightclub
a club with a definite dress code and vibe
and of which I was pretty sure I had neither
comparing my matte-black footwear to that of my friends
a behemoth of a bouncer looked me over and waved me in
At 336 grams (12oz) the Vertex Alpine is certainly not a hefty shoe, but, even so, this spring Arc’teryx released an even lighter model called the Vertex Speed
The Vertex Speed is just 230g (8oz) with a pared down
The Vertex Speed has actually become my go-to multi-pitch walk-off shoe since it packs down to peanuts in a pack or clipped to a harness
The Vertex Speed is available with either a low- or high-cut fabric gaiter
the latter of which is a huge bonus while pounding down scree
It’s a feature I wish the Vertex Alpine came with as well
Arc’teryx has dubbed the Vertex Alpine with a “precision fit” which means that
the shoe will feel quite snug and short across the forefoot
If you are planning to climb or scramble a lot in the shoe
I’d recommend buying your normal street shoe size
If you plan to do equal amounts of running and climbing in the Vertex Alpine
I was concerned with how—or if—the Vertex Alpine would hold up in the field
runner-esque approach shoes appear comfortable and attractive on paper
but I gave the shoe 50/50 odds for staying in one piece
After well over 100 miles (160km) of distance and nearly 10,000 feet (3,000m) of vert
the Vertex has shown zero signs of premature wear
I can’t wait to use the shoes again this summer

SALT LAKE CITY — Skeletal remains found on Friday at Lambert Park have been identified as a 24-year-old woman from Alpine
Lone Peak Police Department said the human remains were identified on Tuesday as Gabrielle Makenna Shull
who police said went missing in January 2024
“Although the forensic anthropology exam is not complete
foul play is not suspected at this time,” the police department said
“Our thoughts are with Gabbie’s family at this terribly difficult time.”
Shull’s family also gave the following statement:
Gabbie’s sweet personality has been and will continue to be greatly missed
Our family is so grateful her remains were found and also to the many
many people who helped in trying to find her
Investigators said the events surrounding her death were still being investigated as of Wednesday

Jack Doohan faced an unfortunate sprint shootout at the Miami International Autodrome
Jack Doohan was left furious with Alpine after a disappointing early exit in Friday's sprint shootout ahead of the Miami sprint race.
The Australian driver delivered his outfit an outraged radio message after being compromised in the opening part of the session by his team-mate.
whilst Gasly progressed to the second part of the sprint shootout at the Miami International Autodrome.
Alpine's plan had been for Gasly to leave the garage directly ahead of the Australian; however
the plan quickly unfolded after Doohan required assistance to avoid hitting the pit wall
This was caused by both cars being released at exactly the same time
due to the poor turning circle on current F1 cars
it has become a common trend to see drivers brush the pit wall when exiting the garage
other cars split the two Enstone-based cars
That’s not acceptable," stated a furious Doohan over the radio.
His race engineer quickly apologised; however
Doohan's radio frustration continued: "If you’re going to send him after me
I can’t turn out and then have to turn out because he’s going to run into me.

Cybersecurity researchers have revealed that Russian military personnel are the target of a new malicious campaign that distributes Android spyware under the guise of the Alpine Quest mapping software
"The attackers hide this trojan inside modified Alpine Quest mapping software and distribute it in various ways, including through one of the Russian Android app catalogs," Doctor Web said in an analysis
The trojan has been found embedded in older versions of the software and propagated as a freely available variant of Alpine Quest Pro
a paid offering that removes advertising and analytics features
The Russian cybersecurity vendor said it also observed the malware
being distributed in the form of an APK file via a fake Telegram channel
While the threat actors initially provided a link for downloading the app in one of the Russian app catalogs through the Telegram channel
the trojanized version was later distributed directly as an APK as an app update
What makes the attack campaign noteworthy is that it takes advantage of the fact that Alpine Quest is used by Russian military personnel in the Special Military Operation zone
the malware-laced app looks and functions just like the original
allowing it to stay undetected for extended periods of time
Besides sending the victim's location every time it changes to a Telegram bot
the spyware supports the ability to download and run additional modules that allow it to exfiltrate files of interest
particularly those sent via Telegram and WhatsApp
"Android.Spy.1292.origin not only allows user locations to be monitored but also confidential files to be hijacked," Doctor Web said
its functionality can be expanded via the download of new modules
which allows it to then execute a wider spectrum of malicious tasks."
To mitigate the risk posed by such threats
it's advised to download Android apps only from trusted app marketplaces and avoid downloading "free" paid versions of software from dubious sources
The disclosure comes as Kaspersky revealed that various large organizations in Russia
have been targeted by a sophisticated backdoor by masquerading it as an update for a secure networking software called ViPNet
"The backdoor targets computers connected to ViPNet networks," the company said in a preliminary report
"The backdoor was distributed inside LZH archives with a structure typical of updates for the software product in question."
Present within the archive is a malicious executable ("msinfo32.exe") that acts as a loader for an encrypted payload also included in the file
"The loader processes the contents of the file to load the backdoor into memory," Kaspersky said
This backdoor is versatile: it can connect to a C2 server via TCP
allowing the attacker to steal files from infected computers and launch additional malicious components
and SOC security to respond quicker and stop breaches early

Alpine has become the first team to be penalised in Miami
The Alpine F1 team has received a €1,000 fine following the sole practice session at the Miami Grand Prix
The fine was handed down to the Enstone-based squad after Jack Doohan was found guilty of speeding in the pit lane during the session
The pit lane speed limit in Miami is set at 80 km/h - however Doohan exceeded this by 17.5 km/h
and was logged doing 97.5 km/h as he entered the pit lane on one occasion
ahead of only the Aston Martin of Lance Stroll
The Australian driver enters the Miami event hoping to secure his first points of the season and add to the tally collected by team-mate Pierre Gasly in Bahrain
The sun had set by the time I reached the top of the skin track on Earthquake Dome
a popular backcountry skiing zone near my home in Mammoth Lakes
It was a February evening and I’d driven ten minutes from my home in town to ski an after-work lap
I’d overestimated my speed and underestimated the low winter sun
and now I was transitioning a pair of uniquely shaped skis—so rockered they looked like a banana—for their first ever lap downhill
I couldn’t see a thing and just prayed I wouldn’t slip and take a pratfall like in a cartoon
A few weeks earlier I sat on a Zoom call with Xan Marshland
Marshland had wanted me to test the Intention 108
the Salt Lake City-based brand’s flagship ski made partially with stringers of an algae-derived plastic
Very few ski manufacturers put polyurethane (i.e
But polyurethane is an engineered material
and vibration damping properties to make the ski do exactly what they want
And only WNDR’s plastic is fully renewable
Marshland believes that not only does the algae make WNDR’s skis eco-friendlier
I’ve tested skis for a living for the last five years
and I have long been skeptical of space-age and eco-friendly materials being responsible for marked increases in performance
But as I’ve spent more and more time on the WNDR Intention 108
it has turned into my favorite ski ever made
the future of WNDR Alpine is unknown at this time
The company recently put all of their skis and snowboards on clearance and seem to have sold the entirety of their backstock
Marshland told me that the brand has some prospective buyers in the wings
hope the brand finds a new home and continues to be a driving force of innovation and sustainability in skiing
Standing atop Earthquake Dome that night and clicking into the skis
it was time for the algae-based plastic to hit the snow
right?) I let my headlamp-equipped fiancée lead
figuring I could follow her light through the maze of tight trees back to the car
quickly-receding glow of white—my only guide
After getting used to the ample rocker (e.g
after a few tumbles in the dark) I began to increase my speed and feel what Marshland had described on our call in the ski’s construction
the polyurethane in its core muting the vibrations that should have been transmitted to my body from the firm and choppy snow that had been sitting for a few weeks since the last storm
As I began to ski the WNDR Intention 108 more and more in the coming weeks
I realized that the plastic was the secret sauce—that it was sustainably sourced was just icing on the cake
Heavier ski boots designed for expert skiers
are made from a heavy polyurethane that is formulated to produce a smooth
progressive flex when a skier drives their shins into it
This ski had the exact same feeling—the dampness
the return of energy that drew me across the fall line
I’ve skied many hundreds of different pairs of skis in my life
but the Intention 108 is hands-down my favorite
and these skis are not just dependable—they’re so much fun
unlocked feel of the Intention 108’s full rocker shape by putting the ski on edge
or fully embrace it by skiing it on a flat base
In steep terrain with firm snow—the conditions many experts will tell you necessitate having camber under your feet—the Intention 108 can pivot and slide
making it easy to hop turn down sketchy stuff
The full rocker profile also makes the Intention 108 is easy to ski in moguls and air off the slightest bump or takeoff
It even carves surprisingly well for its width and lack of traditional camber
I’ve never ridden a ski that possessed such mind-boggling versatility
An obvious sticking point for a lot of skiers will be the Intention 108’s weight
That’s a lot for most skiers to lug uphill
but WNDR doesn’t bill the Intention 108 as a dedicated backcountry ski
If your average day in the mountains has you clocking more than 3,000 to 4,000 feet of elevation gain
But for me, with a lightweight tech binding (a Moment Voyager XIII) and a medium-weight AT boot (the Scarpa Quattro Pro)
I find that I don’t start to drag below 4,000 vertical feet
the ski’s weight can be advantageous—on long tours in the high alpine you often encounter all sorts of weird and difficult snow textures; the Intention’s weight can help mellow out rough conditions
I wish more ski manufacturers would consider putting polyurethane in their products
they’re just more predictable than twitchy
WNDR’s algae-based plastics and resins replace toxic glues and petroleum products in their skis
leading to a ski that’s both easier to recycle and less harmful if it ever does end up in a landfill
skiers who prioritize edge hold in nasty snow will want to opt for a cambered ski
Those skiers are in luck: the Intention 108 also comes in a cambered shape
WNDR made a move last year to make their Intention 108 in the Sideways Sports (SWS) factory in Dubai
The idea was to bring their algae oil technology
to a facility that also makes snowboards for Arbor
Once the factory knows how to use the microalgae-oil plastic
they can use it in other brands’ products
making their product in a facility that uses 100-percent green energy is a huge win
And I’m hugely supportive of the sharing of ideas that could make the snowsports industry less harmful to the environment
The SWS factory also has the capability to produce a binding plate made from the factory’s own reclaimed waste that is 35 percent stronger than the industry standard
That said, making skis in Dubai—far away from the snowsports world—vastly increases product shipping distances, requiring more fuel and energy. Dubai also has a suspect history with labor rights and safety standards that shouldn’t be overlooked. My greenwashing (and sportswashing) antennae tend to prick up when I hear of sustainability and the United Arab Emirates
I am certain that WNDR Alpine is good for the ski industry
I hope the company finds a competent buyer and continues to push skiing forward
you can find me high in the alpine through the summer months with the Intention 108 under my feet

Metrics details
Nutrient resorption is an important strategy for nutrient conservation
especially in permafrost ecosystems where plant growth is limited by nutrients
Based on the measurements mainly derived from tropical
current projections suggest that resorption efficiency is higher for leaf nitrogen (N) than for phosphorus (P) in cold regions
these projections have not been fully validated due to the lack of observations in permafrost ecosystems
we carry out a large-scale sampling campaign along a permafrost transect on the Tibetan Plateau
resorption efficiency is higher for leaf P than N in permafrost ecosystems (75.1 ± 1.8% vs
Our results also reveal that leaf P resorption efficiency is higher in permafrost ecosystems than in global herbaceous plants
while there is no difference for leaf N resorption efficiency
there is a trade-off between leaf N resorption efficiency and soil N mineralization rate
These results illustrate the unique characteristics of plant nutrient resorption in permafrost ecosystems and advance our understanding of nutrient conservation strategies in little-studied permafrost regions
a better understanding and a more precise estimate of leaf nutrient resorption are essential for accurately evaluating plant nutrient status and predicting terrestrial C dynamics under changing environmental conditions
due to the limited number of direct measurements
the relative sizes of leaf N and P resorption efficiency in permafrost zones across a broad geographical scale remain unclear
Sample sizes of leaf N and P resorption efficiencies are 83 and 65 for graminoids
Data are represented as the means ± SE (standard error)
and different letters (unadjusted P < 0.05) represent significant differences (lowercase letters for N and capital letters for P)
These results demonstrate that there is a more severe restriction of P supply across our study area
which could therefore be responsible for the higher leaf P resorption efficiency observed in this study
P concentrations in the senesced leaves would be below the complete resorption boundary (<0.4 g kg−1 for P)
The senesced leaf P concentrations observed in our study were close to the complete resorption boundary at 23 of the 30 sites
suggesting that leaf P resorption proficiency was high across Tibetan permafrost ecosystems
these two lines of evidence support the view that
plants have a high P conservation capacity from senesced leaves
This situation may thus result in a severe restriction of available P for plants and the observed high leaf P resorption efficiency across Tibetan permafrost ecosystems
a Relationship between N concentrations in the mature and senescent leaves
b Association between P concentrations in the mature and senescent leaves
c Linkage between resorbed N:P and leaf N:P concentrations in the mature leaves
d Correlation between log10-transformed resorbed N:P and log10-transformed leaf N:P concentrations in the mature leaves
The gray dashed line in each panel is the 1:1 line
Only significant relationships are shown using solid lines
Error bars denote SE of mean at each site (n = 3)
and P value) are shown for the linear mixed-effects models with two-sided t-tests (unadjusted P < 0.05)
our results illustrated that the three basic strategies existed simultaneously in the permafrost region on the Tibetan Plateau
a Relationship of leaf N resorption efficiency with topsoil N mineralization rate
b Association of leaf P resorption efficiency with topsoil P mineralization rate
A significant relationship is shown by a solid line
Statistics (R2 and P value) are shown for the generalized linear mixed-effects models with two-sided t-tests (unadjusted P < 0.05)
P acquisition by plants can be less reliant on mobile inorganic P derived from soil mineralization
leading to no trade-off relationship between leaf P resorption efficiency and soil mineralization rate as observed here
Our results also showed that there was a trade-off between leaf N resorption efficiency and soil N mineralization rate
but no such trade-off for P: a difference between the N and P cycles within ecosystems that should be taken into account when exploring how nutrient cycles regulate plant C uptake in this little-studied permafrost region
All collected samples of mature and senesced leaves were oven-dried at 65 °C to constant weight and roughly ground with a crusher
A portion of them was then finely ground with a ball mill before chemical analyses
Community-level mature and senesced leaf N concentrations were determined by an elemental analyzer (Vario EL III
Leaf P concentrations were measured with a spectrophotometer (ICAP6300
USA) after a microwave-assisted digestion with H2SO4 and H2O2 at 380 °C for ~3 h
Before the measurement of leaf N and P concentrations
in-house standards (Phenylalanine) were used to calibrate the concentration of total N
and a standard calibration curve for P concentrations was prepared using a serial dilution of inorganic P solution
During the measurement of leaf N and P concentrations
reference materials (GBW10020 GSB-11 Citrus leaves
approved by General Administration of Quality Supervision
Inspection and Quarantine of the People’s Republic of China) were run with the samples to further evaluate the effect of calibration and to check the accuracy of N and P concentrations
The analytical accuracies of the elemental analyzer and spectrophotometer were better than 0.1% for N concentration and 1 ppb for P concentration
leading to the fact that leaf nutrient resorption efficiency could be affected by any potential seasonal variations
more attention should be paid to such potential seasonal variations in order to generate a more comprehensive estimate of plant nutrient resorption across this study region
determines the relationship between senesced and mature leaf nutrient concentrations:
After converting with log10 transformation
a linear regression is shown between log10 (Nusen) and log10 (Numat) as:
By combining Eqs. (1) and (3)
leaf nutrient resorption efficiency can be expressed as:
By converting with a log10 transformation, a linear regression between log10 (Resorbed Nu1:Nu2) and log10 (Leaf Nu1:Nu2) is shown as Eq. (6):
By combining Eqs. (1) and (5)
All aboveground vegetation within the tubes was clipped
and their bottoms covered with nylon mesh bags containing ~5 grams mixed-bed ion-exchange resin (Sigma Amberlite 150 mixed-bed resins)
these resin bags were shaken in 2 M KCl solution for 3 h to saturate exchange sites with K+ and Cl− ions
were then put back in their original locations
and soils at the same depth were sampled near each tube
The resin bags were set out in the field from mid-June to mid-July and removed from mid-September to mid-October 2021
the bags were replaced once a month to avoid oversaturation of the ion-exchange resin
the resin bags were rinsed with deionized water
soil samples from within the tubes were collected
Soil samples and resin bags were both transferred to the laboratory (State·Key Laboratory of Vegetation and Environmental Change
Chinese Academy of Sciences) and stored at −20 °C
they were extracted for 30 min with a 1 M KCl solution at room temperature
The extracted liquids were analyzed for NH4+-N
NO3−-N concentrations using a flow injection analyzer (Autoanalyzer 3 SEAL; Bran and Luebbe
The inorganic P concentrations in the extracted liquids were analyzed using the vanado-molybdate method with a spectrophotometer (UV-2550; Shimadzu
the soil N or P mineralization rate was determined by calculating the difference between the post-incubated amount of inorganic N (NH4+-N and NO3−-N) or inorganic P in the soil and resin bags with the corresponding values in the soil before incubation
These rates were expressed on the basis of the bottom area of the plastic tube and the incubation time (ng cm−2 d−1)
inorganic N or P concentrations of before-incubated soils were measured simultaneously with those of the post-incubated soils and resin bags to reduce systematic errors across different measurement times
during the measurement of soil inorganic N and P concentrations
in-house standards (quantitative inorganic N and P solutions) were run with the samples to check the accuracy of the N and P concentrations
A global dataset was compiled from published datasets before October 2024 by searching the Web of Science (https://webofscience.clarivate.cn)
The final dataset consists of 134 studies containing 998 observations of leaf N resorption efficiencies and 913 observations for leaf P resorption efficiencies
83 and 65 are for N and P resorption efficiencies
while 43 and 27 are for N and P resorption efficiencies
where MLCF is 0.780 for evergreen broadleaves
