Stornes Wins IRONMAN Frankfurt to Become European Champion

June 28, 2026

The drama of IRONMAN Frankfurt started a few days out as temperatures soared during a gripping heatwave that had taken over much of Europe. Forecast temperatures of 40C (104F) left the organization no choice but to shorten the European Championship, reducing the bike to 125km (77.8 miles) and the run to a half marathon. The course changes shifted race dynamics, making the six Kona slots and race predictions more exciting.

Riddle Leads Swim But Pack Stays In Contact

The swim remained unchanged at 3.8km (2.4 miles), but the water, at a bath-like 29C (84F), was still affected by the heatwave and, unsurprisingly, made for a non-wetsuit swim. The course consists of two laps—one of 1.5km and the second of 2.3km—separated by an Australian exit. Starting in ankle-deep water, 59 pro men jostled for position as the race began, but it came as no surprise when South Africa’s Jamie Riddle sprinted into the lead before the first sight buoy.

Vincent Luis, with his calmer swim stroke and short-course speed, moved into the lead shortly after to take over the pace-making. But after the second turn, Luis backstroked and slid back a few swimmers, forcing Riddle to take on the workload at the front with Michele Sarzilla (ITA), Kacper Stepniak (POL), Wilhelm Hirsch (DEU), Jan Stratmann (DEU), Andrea Salvisberg (SUI), and, surprisingly, former pro cyclist Ruben Zepuntke (DEU) all in tow. Race favorites, including current IRONMAN World Champion Casper Stornes and former World Champion Gustav Iden, sat farther back but remained attached to the long, spread-out main pack.

Riddle (sporting the EZ Gain Hydro-Glide under his swim cap) was first onto land at the Australian exit, turning around to see that a large group of about 24 athletes remained in contact, including Magnus Ditlev. Split times were two minutes slower than last year, indicating the heat was already a factor.

On lap two, Stepniak and Hirsch took over the pace-making duties. After each spent a turn at the front, both strategically slid back, leaving Riddle to lead the final quarter of the swim. With a time of 49:16, the South African exited the water first—but he had plenty of company. Notably, Stornes was 18 seconds back, Ditlev 24 seconds, and Iden 30 seconds.

Despite the long run into T1, the front group found itself in tight quarters at the transition bags. Hirsch and Riddle, showing considerably more speed through transition than much of the field, hit the bike course first and clocked the fastest T1 splits.

Guerbeur Dominates Bike Despite Losing Nutrition and Shaky Aerobars

In the early stages of the two-lap bike course, athletes were on the move, as expected. Frenchman Nathan Guerbeur rode into the lead, the Iden-Stornes train made its way to the front, and, with Riddle sitting fourth, Antonio Benito López (ESP) held strong at the back of the five-man lead group.

Ditlev, who hadn’t raced since Marbella last year and had battled illness this season, seemed off to a rough start on the bike. But whether he simply needed to settle after seven months away from racing or was sticking to his pacing plan, Ditlev soon started to do what Ditlev does best. From 90 seconds down after T1, he worked his way to within seconds of the lead pack by the 55km mark, bringing Stepniak, Stratmann, Hirsch, Nick Emde (DEU), and Zepuntke with him.

Luis, who stood to benefit from the shortened course, also appeared off his expected pace early on the bike. Unlike Ditlev, what may have looked like a measured start soon became a clear struggle as his deficit ballooned to 90 seconds by the end of the first lap.

As the pros looped past transition and onto lap two, they merged with the age-group athletes.

Guerbeur, with his rear bottle hanging precariously by only the safety elastic, held a 30-second advantage off the front. The nine-man lead group, which included both Norwegians and a content-to-sit-in Ditlev at the back, appeared controlled and relaxed—but things began to shift as they entered the second half of the bike.

The first drama came when Guerbeur reached back with 45km (28 miles) to go and discovered his rear bottle had bounced off. It took him 12km (7.5 miles) to reach an aid station, and it was teeth-clenching to watch him miss bottles and weave through age-group athletes before finally securing two.

There was significant congestion through the first quarter of the lap, especially on the climbs where amateurs spread across the road two to three abreast and through villages where the roads narrowed. The men navigated the traffic cleanly, but it may have disrupted the group’s rhythm.

As the roads opened up, a clear split formed among the leading men. Stratmann, Benito López, Zepuntke, and Emde sat more than two minutes behind the leaders (90 seconds behind Stornes). Unfortunately, Ditlev had dropped off the lead pack and out of Kona contention, ultimately losing over six minutes by the end of the bike.

Despite missing bottles again at the next aid station, Guerbeur extended his advantage to 50 seconds. But with 10km (6 miles) remaining, his aero bars appeared visibly loose. After moving his bottle to the rear and sitting up on the base bar, he signalled for a mechanic. However, with the finish of the bike so close, he soon settled back into the bars and continued on.

Attacking the final climb, Guerbeur reached T2 with a 1:15 lead and stopped the clock at 2:41:59.

Stornes Speeds to the Lead and Ditlev Claims Final KQ Slot

Looking calm and moving well as he racked his bike, Guerbeur executed a smooth, controlled transition. Likewise, Iden and Stornes looked relaxed, chatting to one another in Norwegian while putting on their shoes.

Riddle had a different experience, having to run back to the racks after grabbing the wrong bag and losing valuable time to his competitors.

Stornes, running like the World Champion he is at 3:29 per kilometre pace, made quick work of moving into second place. As soon as he got sight of Guerbeur, he seemed to hit the turbo button, dropping down to 3:09/km pace. At the 5km mark, Stornes made the pass, and the two competitors grabbed hands in a showing of mutual respect.

Like his compatriot, Iden was also on the move. At the 10km mark, he too passed a fading Guerbeur. Riddle, who tried to stay with Iden through the opening kilometres—perhaps paying for that decision later—was eventually dropped and fell prey to a charging Benito López.

But with a 1:12:19 run split, it was the Stornes show from start to finish. The World Champion claimed the European title in 4:50:23, not even slowing as he accepted a Norwegian flag a few hundred metres from the finish.

Iden finished second and, crossing the line with his signature heel-click jump, Benito López took third.

Other standout runs included Michele Sarzilla, who climbed from 22nd off the bike to sixth overall with a 1:14:09 half marathon.

The Kona slots went to Benito López, Stepniak, Guerbeur, Riddle, Stratmann, and, after a 1:15 run split to finish 11th, Ditlev.

“My body is built for this,” Stornes said in his post-race interview.

“ I struggled a little bit on the swim, especially with my stroke after my crash,” he continued, referencing his bike crash two weeks ago during an altitude training camp in Saint Moritz, Switzerland. “The last week has been so painful in my ribs, so I was happy when we were done with the swim,” he revealed.

“When I came to the bike, it felt a little bit chaotic the first hour, and then [I settled] into it and got off the bike together with Gustav and Jamie Riddle. I just sat into my own pace on the run and kept it there. I got to a ninety-second gap out for the second lap, and then I think I had two minutes or something on Gustav in the end,” he explained. “So, yeah, I’m happy with my race and, yeah, felt in control, actually,” he concluded.
