In 2023 and 2024 he broke the world record following dedicated and well-structured training in the months leading up to the race, but this year his approach was completely different. Just one week ago, he qualified for the IRONMAN World Championship in Hawaii after a tough day in Frankfurt, but because that race was shortened due to the heat, a start in Roth suddenly became possible – and the Dane seized the chance when the three-time champion found himself holding a start slot on Tuesday morning.

It was a great opportunity to get a solid IRONMAN in the legs before the build-up toward the World Championship in October – and after a difficult year in which illness has ruined most of his races.

France's Sam Laidlow completed what otherwise looked like a suicide mission and won for the second year in a row in the world record time of 7:21:04, while Kristian Blummenfelt ran a 2:29 closing marathon to take second place ahead of Rico Bogen, who claimed an impressive third in his debut over the full IRONMAN distance.

A cunning swim plan paid off

A group of the sport's strongest swimmers had made a plan before the start: to work together and swim as fast as possible in order to open a gap heading onto the bike to powerful cyclists like Magnus Ditlev and Kristian Høgenhaug and fast runners like Kristian Blummenfelt and Patrick Lange.

The plan worked, and a trio consisting of last year's winner Sam Laidlow and the two Germans Rico Bogen and Jonas Schomburg had opened a big gap after the 3.8 km swim to both Blummenfelt and Ditlev. All three are strong in the water and on the bike, and with a non-wetsuit swim due to the water temperature, conditions favored the fastest swimmers.

The trio had 3 minutes on Blummenfelt and 4.5 minutes on Ditlev, and although Magnus Ditlev closed the gap to Blummenfelt within the first 20 km of the bike, he could not shake the Norwegian. The Dane tried repeatedly to drop the pre-race favorite with hard surges, but every time a gap opened, the Norwegian clawed his way back into the Dane's slipstream, and eventually the Dane sat up and let the Norwegian set the pace. The two have history on the bike, with Ditlev trying to drop the Norwegian, who in turn has been like a hungry mosquito on the hunt for the Dane. The pair lost significant time to the riders up the road, however, as Bogen and Laidlow continued their two-man effort, while Schomburg lost nearly 7 minutes over the final 60 km – and Blummenfelt and Ditlev were almost 16 minutes off the front after the 180 km bike leg.

The run was good, but the gap was too big

Ditlev opened a small gap heading into T2, and out on the closing 42.2 km run, Ditlev and Blummenfelt could run side by side in pursuit of the front three.

After 6 km, Blummenfelt started to wind up the pace, and the Dane had to let him go. Up front, Bogen quickly had to let Laidlow go, and while Blummenfelt was reeling in the leaders, he was still more than 10 minutes back after the first half marathon.

At the front, Laidlow was on his way to smashing the world record – if he could hold the pace. Bogen faded quickly, and Schomburg was passed by Blummenfelt for 3rd place after roughly 26 km. Over the final kilometers, both Bogen and Laidlow were in serious trouble, and the lightning-fast Norwegian first ate up the gap to the German, and although Frenchman Laidlow was grimacing over the final 15 km of the run and was reduced to walking a couple of times, he held on and crossed the finish line in 7:21:04 – a good two minutes faster than Magnus Ditlev's course record from 2024 (which was also the world record at the time) – and he clipped a few seconds off Blummenfelt's world record from Texas in April.

Blummenfelt never caught Laidlow, but he ran sub 2:30 for the closing marathon for the first time, posting a run split of 2:29:33.

The Dane crossed the line in 6th place with a marathon time of 2:37:33.

Next up for Magnus Ditlev is the IRONMAN World Championship in Hawaii in October.
