IRONMAN 70.3 World Championship Nice 2026: Form Guide and Athletes to Watch
The IRONMAN 70.3 World Championship returns to Nice, France, for a two-day format: the women’s race on Saturday 12 September 2026, followed by the men’s race on Sunday 13 September 2026. Both fields are stacked with multiple past champions, making this one of the most competitive World Championship start lists in years.
Women’s Race: Saturday 12 September
Lucy Charles-Barclay heads into Nice as defending champion, chasing a third 70.3 world title. Standing in her way is Taylor Knibb, a three-time IRONMAN 70.3 World Champion who has finished on the podium at every edition she’s contested since 2021 but is racing the Nice course for the first time. Also on the start line: Solveig Løvseth, the reigning IRONMAN World Champion at full distance, Laura Philipp, the 2024 IRONMAN World Champion, and Kat Matthews, the defending Pro Series champion — five of the best middle-distance triathletes in the world on one start line. The Canadian contingent is led by Paula Findlay, alongside Tamara Jewett, Amélie Kretz (making her IRONMAN 70.3 World Championship debut), and Kristen Marchant.
Men’s Race: Sunday 13 September
Jelle Geens defends his title unbeaten at this level — he’s won both IRONMAN 70.3 World Championships he’s started, in Taupô (2024) and Marbella (2025). He’ll face all three of the men who beat him to previous world titles: Rico Bogen (2023 champion), Kristian Blummenfelt (2022 champion), and Gustav Iden (2019 and 2021 champion). Add in Marten Van Riel, the 2024 T100 World Champion, Casper Stornes, reported as the reigning IRONMAN World Champion, and Hayden Wilde, the dominant force on the T100 circuit this season, and it’s arguably the deepest men’s field the 70.3 Worlds has ever assembled — a reported 72 professional men on the start list. Canada’s challenge comes from Lionel Sanders, Blake Harris, and Zachary Bernier-Michaud.
What to Watch For
With four past 70.3 world champions in the men’s race and three of the last four years’ champions among the women, this is less a coronation and more an open contest — expect the swim and bike legs to set up a genuine run race in both fields rather than a solo breakaway. Charles-Barclay’s and Geens’s unbeaten records at this distance make them the favourites on paper, but the depth of both fields means a small mistake in the French heat could open the door for any of the challengers.
How to Watch
IRONMAN typically streams the World Championship live via the IRONMAN YouTube channel and app — check the official IRONMAN Nice event page closer to race day for confirmed broadcast times, since these can shift.
