Magnus Ditlev smashes the fastest IRONMAN ever in Florida as Alanis Siffert wins her first

Dane Magnus Ditlev left Kona and the latest IRONMAN World Championship deeply disappointed, having led for long stretches before cracking on the marathon in the unforgiving furnace of the Energy Lab. Florida gave him a perfect chance to settle the score. He didn't just win: his 7:19:17 finish sets a new benchmark for the IRONMAN distance.

Sixth out of the water, Ditlev quickly took control on the bike. He covered the 180 km in 3:51:16 and rolled into T2 with more than eleven minutes in hand on his chasers. That also took two minutes off the previous IRONMAN bike record, set by Sweden's Robert Kallin (3:53:12) at IRONMAN Kalmar last August.

But the most impressive part was still to come. After that bike demonstration, the Dane followed up with a 2:33 marathon. His final time is almost two minutes under the previous best IRONMAN mark, set by Kristian Blummenfelt with 7:21:12 at IRONMAN Cozumel in 2021, and also under the 7:21:04 Frenchman Sam Laidlow ran at Challenge Roth last July.

Top three earn Kona 2027 slots

Behind him, the fight for the remaining podium spots was far tighter. American Rudy von Berg secured second place more than 14 minutes behind the winner. Fellow American Matt Hanson completed the podium by reeling in Sam Long late in the marathon. Long will have to go through another IRONMAN in his 2027 season if he wants to earn his slot for the 2027 Kona World Championship. Only the top three finishers of the day punched a direct ticket to Hawaii for the 2027 IRONMAN World Championship.

Among the French pros, the fastest was Simon Viain, who wrapped up his 2026 season in Panama City. He finished 12th overall with a sub-8 (7:54). Out of the water in 12th, the Drôme native then posted the 15th-fastest bike split and the 11th-fastest run (2:47:32). Paulin Philippe finished 23rd among the pros, and Andrea Cloarec 28th.

Alanis Siffert opens her IRONMAN account

On the women's side, Switzerland's Alanis Siffert - winner of the L-distance triathlon in Alpe d'Huez in July - reached a major milestone in her career by winning her first IRONMAN.

Already a winner at Challenge Roth and bronze medallist at the 2026 IRONMAN 70.3 World Championship in Nice, she confirms an excellent season. She had chosen to skip the IRONMAN World Championship in Kona this year. This win in Florida now gives her a shot at lining up in Hawaii in 2027.

An inseparable duo forms on the bike

The women's race quickly turned into a duel between Siffert and Britain's Holly Lawrence. First out of the water, the Swiss athlete battled her rival for a long time over the 180 km of riding. Lawrence eventually reached T2 almost two minutes ahead of Siffert, and more importantly with a comfortable lead of nearly twenty minutes over Germany's Laura Jansen, third at that point.

The marathon was about to reshuffle the deck. Siffert gradually closed the gap before passing Lawrence around kilometer 7. Once in front, the Swiss was never threatened and kept stretching her lead all the way to the line. She won by more than 16 minutes over Lawrence. Laura Jansen rounded out the podium almost 25 minutes behind Siffert and also earned her slot for Kona 2027.

With that weight off their shoulders, the day's podium finishers can look ahead to next season with a lot more peace of mind.
