The world’s best middle-distance triathletes will descend on Nice next month for the 2026 Precision Fuel & Hydration IRONMAN 70.3 World Championship – and Britain will have plenty of interest in both professional races.
Reigning champion Lucy Charles-Barclay heads the women’s field as she bids for a third IRONMAN 70.3 World Championship title, while fellow Brit Kat Matthews arrives in France in excellent form.
More than 140 professional athletes are set to race across the two days, with the women’s championship taking place on Saturday 12 September and the men’s race following on Sunday 13 September.
A total professional prize purse of $500,000 is up for grabs, with the men’s and women’s champions each taking home $75,000.
Charles-Barclay targets third title
Charles-Barclay returns to the championship as defending champion after winning in Marbella last November.
The British star is a two-time IRONMAN 70.3 World Champion and will be racing over the distance for the first time since that victory, with a third title now firmly in her sights.
Standing in her way is a formidable women’s field led by three-time champion Taylor Knibb (USA).
Knibb has finished on the podium at every IRONMAN 70.3 World Championship she has contested since 2021 and was runner-up to Charles-Barclay in Marbella. However, Nice will be a new venue for the American.
There will also be home hopes for Marjolaine Pierré, who has already enjoyed a strong 2026 season, including victory at IRONMAN 70.3 Aix-en-Provence.
Norway’s Solveig Løvseth will also be one to watch. The reigning IRONMAN World Champion has followed her breakthrough victory in Kona last year with a string of impressive performances, including second at IRONMAN 70.3 Oceanside and victories at IRONMAN Texas and IRONMAN Hamburg this season.
And then there’s Kat Matthews.
The British athlete has already won three races in 2026 – IRONMAN New Zealand, IRONMAN 70.3 Geelong and IRONMAN 70.3 Elsinore – and has twice finished runner-up at the IRONMAN 70.3 World Championship.
Matthews finished second behind Knibb in both 2023 and 2024 and will be looking to go one better in Nice.
The women’s field also includes former IRONMAN World Champion Laura Philipp, who won the IRONMAN World Championship in Nice in 2024, as well as Paula Findlay, Julie Derron and Imogen Simmonds.
Geens faces strong challenge in men’s race
The men’s race is headed by defending champion Jelle Geens, who produced one of the closest finishes in IRONMAN 70.3 World Championship history in Marbella last year.
Just three seconds separated Geens and Kristian Blummenfelt after 113km of racing, with the Belgian taking his second consecutive title.
Blummenfelt will be back in Nice and has already beaten Geens once this season, winning IRONMAN 70.3 Geelong in March.
The Norwegian has also enjoyed victories at IRONMAN 70.3 Oceanside and the IRONMAN Texas North American Championship this year, adding to his impressive CV that includes Olympic gold and both IRONMAN and IRONMAN 70.3 World Championship titles.
He won’t be the only Norwegian threat.
Current IRONMAN World Champion Casper Stornes will be looking to add another major title after winning the IRONMAN European Championship in Frankfurt in June.
Gustav Iden, meanwhile, returns to the venue of his first IRONMAN 70.3 World Championship victory in 2019.
Germany’s Rico Bogen is another former champion in the field, having claimed the 70.3 world title in 2023, while Jonas Schomburg will add further strength to the German challenge.
Plenty of Olympic pedigree
The men’s start list also includes a host of athletes with Olympic experience.
Olympic medallists Vincent Luis, Hayden Wilde, Morgan Pearson, Sam Dickinson and Seth Rider will all line up in Nice.
Belgium’s Marten Van Riel will also be one to watch.
Van Riel has won every IRONMAN 70.3 race he has started since 2019 and has already enjoyed a hugely successful 2026, winning IRONMAN Lake Placid and IRONMAN 70.3 Elsinore while finishing second at IRONMAN Texas.
A spectacular Nice course
The championship will showcase one of the most iconic courses in the IRONMAN calendar.
Athletes will begin with a 1.9km swim in the Mediterranean, starting from Plage des Ponchettes on Nice’s famous seafront.
The 90km bike course then heads into the Alpes-Maritimes, with winding roads, mountain scenery and the challenging climb of Col de Vence providing the main test.
Finally, athletes return to the coast for a 21.1km run along the Promenade des Anglais.
With a fast, spectator-lined finish and the Mediterranean as a backdrop, Nice promises a dramatic setting for two days of world championship racing.
The event is also the penultimate race of the 2026 Experience Oman IRONMAN Pro Series, with up to 3,000 points available to each champion before the series concludes at the IRONMAN World Championship in Kona in October.
How to watch
Live coverage of both professional races will be available internationally via the IRONMAN YouTube channel, ironman.com/proseries and DAZN, with additional regional coverage also available through a number of broadcasters.
The women’s race takes place on Saturday 12 September, followed by the men’s race on Sunday 13 September.
