Frenchman Vincent Luis produced a remarkable performance to win his debut IRONMAN World Championship – in what is due to be the final season before he retires.

The one-time short-course specialist was always in the hunt on a hot and humid day in Hawaii, maintaining his position among the lead pack throughout the swim and bike, before then dropping the great Kristian Blummenfelt in a hugely dramatic marathon that also saw Sam Laidlow pull out with an injury issue.

And when long-time leader Magnus Ditlev crumbled on the Kona roadside, it was Luis who stepped up to take his place at the front of the pack, crossing the line ahead of Gustav Iden, who crucially had been punished with a three-minute bike penalty that ultimately cost him the win.

Blummenfelt, who had come into the race as one of the clear favourites, did threaten to make his move midway through the marathon, but he faded into eighth place, and it was American Matthew Marquardt who completed the podium.

Swim – Blummenfelt holds on to leaders

The men got underway, as a healthy early-morning swell ensured there would be some tricky, choppy swimming conditions in Kailua Bay to contend with.

Almost immediately, the field started to thin out as members of the much-discussed WhatsApp group looked to press the early pace and make a telling move.

The likes of Jonas Schomburg (GER), Wilhelm Hirsch (GER), Jamie Riddle (SAF), Marten Van Riel (BEL), Patrick Lange (GER), and Menno Koolhaas (NED) were positioned among a sizeable but stretched-out lead group.

Just as the field had done at Challenge Roth and the 70.3 World Championships, it seemed there was a clear plan to try and put as much time and water between the front and danger man Kristian Blummenfelt (NOR) as possible.

However, as the athletes were being bounced around by the swell, it was clearly not at all easy for them to make their getaway, and Blummenfelt was able to cling on to the lengthy lead pack and ensure that he was never more than 30 seconds behind.

The opening 1.2km was completed in 14 and a half minutes, which was probably a little too slow for the likes of Riddle, who had made it very clear that he would do everything within his power to speed things up and go out as fast as possible.

At the turnaround, there were 20 to 30 swimmers within just 30 seconds of one another, with France’s Pierre Le Corre taking turns with Hirsch, Riddle, Frederick Funk (GER), Ven Reil and Schomburg at the head of the race.

Blummenfelt, having been beaten into second place at both Roth and the 70.3 Worlds after leaving himself with simply too much to do on the runs, was well aware of the tactic expected to be deployed against him and was able to maintain his position at the back of those leaders.

However, he was made to work even harder as they turned and made their way back to shore, with the significant swell now very much in their favour.

At one point it did look as though Blummenfelt might be dropped, but the big Norwegian dug deep and would have been delighted to exit the water in 24th place, only 31 seconds behind Van Riel, who was first to reach dry land in a time of 48:17.

Koolhaas was second, followed by a group that included Hirsch, Matthew Marquardt (USA) – who had pulled off a brilliant swim – and Le Corre, Lange and Sam Laidlow (FRA), who were all within 30 seconds of the Belgian.

The next group out of the water included former champion Gustav Iden (NOR), but he was now 1:51 back from the leaders and would need to play catch-up on the bike.

Bike – Magnus Ditlev storms through the field

A frantic T1 saw Koolhaas come out first for the bike leg, closely followed by Hirsch, Van Riel, Vincent Luis (FRA) and Lange.

However, the Dutchman wouldn’t stay at the front for long, as some of the big hitters started to work their way up through the tightly packed field behind him.

Schomburg, who had started the bike in 12th position and +00:41 to Koolhaas, was the big mover in the early stages; however, Marquardt (21st, +1:00), Blummenfelt (22nd, +1:01), Laidlow (24th, +1:25), Iden (27th, +2:14), Italian Gregory Barnaby (28th, +2:15) and even Dane Magnus Ditlev (30th, +3:17) would all put the pressure on as they made their way across the Big Island.

The early morning clouds and rain had, by now, cleared for some bright sunshine and fierce humidity, conditions which seemed to cause big problems for the likes of Lange – who was forced to stop while clearly struggling – and Van Riel, who was seen vomiting.

Lange did press on for a short while, but the three-time former champion and course record holder would eventually accept defeat and pull out of what will be his final appearance at Kona in a career which has truly graced the sport of triathlon.

Schomburg may have taken over at the head of the race, but the group of chasers behind him was looking menacing, with Laidlow, Marquardt, Barnaby and Luis making impressive gains as they powered along the Queen Ka’ahumanu Highway.

That group was added to by Ditlev and Iden at the 88km mark, and while Blummenfelt had at one point dropped back to more than 3:30 behind, he too started to put on some pedal power and was able to reconnect himself with the business end of the race.

As they reached the turnaround point at 96km, Schomburg was still looking in good shape and had a 52-second lead over Marquardt, while Ditlev (+1:20), Barnaby (+1:21), Riddle (+1:32), Iden (+1:58), Luis (+2:01) and Van Riel (+2:05) were in hot pursuit.

Laidlow (+2:19) and Blummenfelt (+2:32) were also not too far behind and well within a distance which could make them dangerous as the race progressed.

The race would then change dramatically as the riders made their way back down Hāwī, looking to make use of the tailwinds which had made life so difficult on the climb but which would now power them on the descent.

Schomburg seemed to suffer a severe bout of cramps at the 110km mark, allowing Marquardt, Ditlev and Barnaby to power past him. Indeed, it looked to be a serious issue for the German, as by the 132km point he had dropped to tenth, allowing Laidlow, Luis, Iden and Blummenfelt to make their moves.

A crazy bike leg then took another major twist when leader Marquardt was shown a yellow card and ordered to serve a penalty, a nightmare for the American, who dropped from first all the way back to ninth as a result.

And so it was Ditlev who would end up leading the riders through to T2, the man who had started the leg back in 30th place and more than three minutes adrift, completing his bike with a time of 4:06:47.

While it was no surprise to see Laidlow arrive in T2 next (+1:27), it was perhaps a shock to see Marquardt coming in next, the American having recovered incredibly well from his penalty to sit only +2:23 to the leader.

Barnaby came in fourth (+3:34), Blummenfelt was fifth (+6:02), Luis was sixth (+6:04) and Van Riel had recovered from his sickness to arrive in eighth (+6:29).

Frustratingly for Iden, he too was handed a penalty and came home in ninth at +9:19 to the leader. One of the biggest movers was Sam Long (USA), who completed the bike in a time of 4:12:50 and jumped from 42nd place to round out the top ten.

The order at the bike finish:

Run – Luis takes advantage of Ditlev’s stumble

As Ditlev exited T2 with his narrow lead over Laidlow, the expectation was for the Frenchman to start hunting down the Dane as they set out on the marathon – but an already dramatic men’s race was about to throw yet another shock at us.

The run had barely got started when Laidlow was seen walking through one of the very early aid stations. Rather than fatigue, it seemed he was clutching and shaking his legs in an attempt to release some tension.

His place in second was swallowed up by Marquardt, and then Barnaby also passed him as it very quickly became clear that one of the pre-race favourites was not going to finish.

Sure enough, within minutes, Laidlow was on the side of the road being interviewed by the IRONMAN presenters on their YouTube feed, explaining how he had been struggling with the vascular condition iliac artery endofibrosis – a problem caused by repetitive hip flexion, which leads to arterial wall thickening and reduced blood flow.

It meant that Ditlev was now well ahead and very much in pole position to win his first title, having previously finished second in 2024 and third when the race was held in Nice a year earlier.

The drama, however, was nowhere near over as the race simply boiled down to how six athletes – Ditlev, Marquardt, Barnaby, Luis, Blummenfelt and Iden – could manage themselves and the conditions as the Hawaii humidity started to take effect.

Ditlev’s lead was healthy as they hit the 20km mark, as he sat +4:26 to Marquardt, +4:41 to Blummenfelt, Luis and Barnaby – who were running close together – and a huge +6:44 on Iden.

Indeed, Iden had been close to nine minutes behind when he started the run due to his three-minute penalty, but he was flying through the field, constantly posting the fastest run splits and putting himself into serious contention for a shot at the podium.

As they reached the 30km point, Ditlev was clearly starting to tire, and the chasing pack sniffed their opportunity to move in for the kill. However, somewhat surprisingly, it was not Blummenfelt who led the charge; it was Luis.

Blummenfelt was dropped with an incredible burst of pace from the Frenchman, and even Marquardt and Iden suddenly found themselves ahead of the pre-race favourite as he dropped back down the running order.

Looking incredibly strong, Luis was tracking Ditlev at pace, and when the Dane started walking through aid stations and stopping for additional ice to put in his cap, it was surely only going to be a matter of time before the Frenchman took the lead.

The pain coursing through the body of Ditlev was clear to see as he continued to stop and stutter along the Kona roadside, and Luis just stormed past him with ease, closely followed by the brilliant Iden, who was now his closest challenger.

For a short time it looked as though Iden might just catch his rival and set up a thrilling sprint finish, but the Norwegian had clearly spent a great deal of energy in hauling himself back up into contention, and his challenge petered out.

Luis was even afforded the opportunity to give a few high-fives and do a little celebrating as he pounded down the finishing chute with a smile wider than any ever seen on the Big Island.

His marathon time of 2:38:36 gave him an overall finish of 07:47:27, while Iden’s 2:36:58 saw him cross the line in 7:49:03 – the three-minute penalty that he picked up on the bike leg clearly proving so very costly.

Third place went to American Marquardt, who had dug deep to secure a podium place; his 2:43:58 marathon giving him an overall finishing time of 7:49:59.

Barnaby was fourth, Le Corre had managed to climb into fifth, Long was sixth, Schomburg was seventh, and Blummenfelt – who once again misses out on the season’s biggest prizes – came home in a very disappointing eighth.
