NICE, France (Sept. 12, 2026) /ENDURANCE SPORTSWIRE/ – Taylor Knibb (USA) has dominated the field to win the 2026 Precision Fuel & Hydration IRONMAN^® 70.3^® World Championship in Nice France, claiming her fourth world title on Saturday.

Knibb was untouchable as she took control of the race early on the bike and never looked back, crossing the line to win the World Championship in 4:19:24, more than four minutes ahead of Julie Derron (CHE), with Alanis Siffert (CHE) third.

Saturday’s victory was Knibb’s fourth IRONMAN 70.3 World Championship in the last five years, with the American pleased with her result and the way she is progressing as an athlete.

“The climbs were great, I loved them, and then the descents were actually fun, I felt great coming back in and was like, ok good, you didn’t overcook yourself,” said Knibb. “Then heading onto the run was hard, I think it just got hot, running under the hills it was actually cooler. The last 10k got really hot and the run was a slog, definitely the last 10k, but I made it to the finish line this time.

“This one is very special and I am just very grateful, once you feel the other side, you just have a lot more gratitude because I can tell you for New Zealand for my third, I was not a happy camper and I was not happy with my race and I think that version of Taylor would have been very pissed on this race because of the last 7-8k of the run. But at the end of the day, I did what I needed to do and so I need to be grateful for that and excited for what’s to come,” said Knibb.

For Julie Derron it was a second place in her second visit to the IRONMAN 70.3 World Championship following a fifth-place finish in New Zealand in 2024, running her way through the field and onto the podium after coming off the bike in 11^th.

“I had a bit of a slow start but I made up for it and I finished strong, I’m super pleased that I had the run legs today to run myself onto the podium, that was the aim coming off the bike, to then play a bit of Pac-Man to make it up the ranks as far as I could,” said Derron. “I knew Taylor was unreachable, but I kept getting the splits to go for second and that was the aim. To finish second at my first World Championship, yes, I’m super pleased.”

Fellow Swiss athlete Alanis Siffert was making her IRONMAN 70.3 World Championship debut on Saturday, with the 24-year-old impressing on her way to third place.

“It was just amazing, I still cannot believe it, third place with such a strong field. It’s so nice to be sharing the podium with my teammate Julie, and sharing this with my family, everyone was here, and it was a super hard race,” said Siffert. “I came out the water with the front group, I was super stoked then went on the bike and it was a super hilly course and I love a hilly course, so I thought just do what I normally do and go for it and I really enjoyed the descent. But the run was a real battle, I knew the podium was going to be made on the run, so I just had to give everything I had.”

2026 Precision Fuel & Hydration IRONMAN 70.3 World Championship Women’s Race Recap

Almost 50 of the world’s top professional female triathletes hit the water for the 1.9km ROKA swim in the crystal-clear Mediterranean Sea, starting from Plage des Ponchettes beneath the stunning backdrop of the French Riviera. A lead pack quickly formed in the early stages with Sophie Evans (GBR) leading the way, closely followed by Lena Meißner (DEU) and Jenna Campbell (USA). The top seven athletes were covered by just eight seconds through the first 1.5km, with American duo Taylor Knibb and Kirsten Kasper in the middle of that leading pack.

Evans held onto her lead as she exited the water, finishing the swim in 25:49, just two seconds clear of Meißner, with Campbell just behind in third. Knibb returned to shore nine seconds off the lead in fifth position, with the top 14 covered by 25 seconds. From there it was more than a minute to the chasing pack, led by Julie Derron, Marjolaine Pierré (FRA) and Ellie Salthouse (AUS).

Kirsten Kasper was the first athlete to take to the ZOOT bike course, just ahead of Meißner and Imogen Simmonds (CHE). Simmonds moved to the front in the early, flat, kilometres heading out of Nice, with Alanis Siffert hot on her heels before taking the lead. Within the first 10km Knibb made her move, taking control of the bike leg at the first hint of a climb, opening up a 30 second gap by the time she hit the 13km mark, with the gap quickly blowing out to more than two minutes over Simmonds 10km later. Knibb continued to power ahead, at the 30km mark the lead was over four and a half minutes, with Siffert moving into second and France’s Audrey Merle third.

As the athletes hit the daunting Col de Vence climb Knibb showed her cycling prowess, extending her lead over Siffert to more than six minutes, with Simmonds just behind in third. Once they began to make their way back down towards Nice the chasers began taking a little time out of Knibb, with Marjolaine Pierré the big mover, jumping up to second at the 70km mark. While Knibb was still in control of the race, Pierré, Siffert and Simmonds closed the gap slightly to five and a half minutes.

Knibb returned to Nice and came off the bike with an almost four-and-a-half-minute lead over Pierré, with Simmonds another minute behind in third. Knibb picked up on the run where she left off on the bike, extending her lead over the opening kilometers of the HOKA run course, with Pierré holding onto second, while further back Derron was the big mover, surging from 11^th off the bike to fifth within the first five kilometers. While Knibb was in control at the front there was plenty of movement behind her, with Siffert initially moving into second before Derron pushed through with nine kilometers to go, and with the gap to Knibb unsurmountable she locked down her spot on the podium.

Knibb recorded a 1:17:56 half marathon on her way to her fourth World Championship title, with Derron setting the quickest run of the day for second overall, and Siffert holding on for third.
