What to Expect at the 2026 IRONMAN 70.3 World Championship in Nice

The 2026 IRONMAN 70.3 World Championship is set to go in Nice, France, this weekend. With more than 6,500 athletes ready to toe the start line in the Mediterranean Sea, there are countless stories waiting to be told. Slowtwitch is in Nice ready to deliver many of those stories in the lead-up to and after the races, so be sure to follow along so you don’t miss anything. For now, here is everything you need to know as a busy week kicks off in the Côte d’Azur.

The Pro Women

The two pro races are stacked with top athletes (there is a world championship on the line, after all). The women’s event is headlined by three-time 70.3 world champion Taylor Knibb of the U.S., two-time 70.3 world championship runner-up Kat Matthews of the U.K., defending IRONMAN world champion Solveig Løvseth of Norway and Germany’s Laura Philipp (who won her IRONMAN world title in Nice in 2024).

There is a lot on the line for all of these women. Knibb is looking to win a fourth 70.3 world crown (which would bring her within one of tying Daniela Ryf’s record of five) after a second-place finish in Marbella, Spain, last year.

Matthews has finished second at the 70.3 or IRONMAN world championships five times since 2022. It’s an incredible resume, but she is certainly eyeing the top of the podium as she prepares for Saturday’s race.

Løvseth has been one of the most dominant women on the IRONMAN circuit over this season and last. A 70.3 world title would make her just the fifth woman to secure a full-IRONMAN and 70.3 world championship — and she is still only 27 years old. (Ryf has accomplished this feat, as well as Mirinda Carfrae, Leanda Cave and Lucy Charles-Barclay.)

The same can be said for Philipp, who would not only become the fifth woman to win both titles, but also the first woman to win the two at the same venue. (Kristian Blummenfelt is currently the only athlete to have won both titles in the same place, grabbing his 70.3 and IRONMAN world titles in St. George, Utah.)

Both Løvseth and Philipp are also fighting for the top spot in the IRONMAN Pro Series ranks. Philipp currently sits in first, but she is only a couple of thousand points ahead of the young Norwegian, who is presently ranked fifth. (Two-thousand points may seem like a lot, but the winner on Saturday will earn 3,000.) Both have yet to reach their race limit (five races count for the overall title, with a maximum of three of those being full-distance races), so there will still be lots on the line when the pair get to Kona in October.

The list of other women to watch out for is long, as this is a deep field. France’s Marjolaine Pierré, who was fifth at the 2025 70.3 worlds and will be racing on home soil, is always a threat for a big result. Belgium’s Hanne De Vet is having a strong season that includes a third-place finish at 70.3 Boise. Canada’s Paula Findlay is fresh off a win at her IRONMAN debut in Lake Placid. Switzerland’s Julie Derron has three wins in four races this year (and the fourth was a second-place finish), making her one of the most consistent women on the pro tour at the moment.

The race really could go any direction. It will be an extremely fun one for fans of the sport to watch on Saturday.

The Men’s Race

The pro men’s race is just as impressive as the women’s. Some of the bigger names to watch are two-time defending world champion Jelle Geens of Belgium, the aforementioned Blummenfelt and his Norwegian training partners, IRONMAN world champions Casper Stornes and Gustav Iden, and New Zealand’s dual Olympic medallist Hayden Wilde.

If Geens can win on Sunday, he will become the first man to win three 70.3 world crowns (joining Knibb and Ryf as the only athletes to do so). Blummenfelt is looking for revenge on Geens, who beat him to the line in a thrilling sprint finish last November in Marbella to take the world championship win.

Stornes and Iden made up two parts of the IRONMAN World Championship podium in Nice last year (along with Blummenfelt), and they would both like to run it back this weekend. Stornes won in Nice last year ahead of Iden, who won the 70.3 world title on this same course back in 2019.

Wilde has been the man to beat on the T100 circuit for the past year and a half. While he has been virtually unbeatable in most of those 100-kilometre races, he has yet to reach that level in 70.3 racing. He came close to a 70.3 world championship in 2024 on home soil in Taupo, New Zealand, but he faded to second place behind Geens. He has raced one 70.3 this season — in Geelong, Australia — an event in which he finished third behind Blummenfelt and Geens.

Other men to watch include Germany’s Jonas Schomburg (who was second at 70.3 Oceanside earlier this year and just won his first IRONMAN in Sweden last month), his compatriot and the 2023 70.3 world champ Rico Bogen, Belgium’s Marten van Riel (winner of IRONMAN Lake Placid and 70.3 Elsinore in 2026) and American Jason West (who is coming off of a solid win at 70.3 Northern California last month) — among others.

Much like the women’s event, the men’s world title is very much anyone’s to steal, making Sunday the weekend’s second day of can’t-miss racing.

Age Group Racing

There are 152 pros set to race, but more than 6,300 age group athletes will be competing in Nice on the weekend as well. Coming from 130 countries, 3,000 women and 3,500 men will hit the course to chase personal records, age group world titles and the world championship finish line. Of those 130 countries, the five with the most athletes are, in order, the U.S., France, Germany, Brazil and the U.K.

The average age of the thousands of athletes is 43, while the youngest on the start list will be 18-year-old American Olivia Morabtio and the oldest Germany’s Gotthard Winkler, 82. Among the many age groupers, there are 11 returning to defend their 70.3 world titles from 2025.

From start to finish, fastest to slowest, it will be a wildly exciting weekend of racing in Nice. Once again, be sure to follow along as the week goes on to get daily updates and stories from the event.
