On Sunday, 13 July, nearly 60 professional triathletes will head to the south coast of Wales for the first time to compete in the IRONMAN® 70.3® Swansea triathlon, the 12th event in the 2025 IRONMAN® Pro Series. The event will offer a maximum of 2,500 points towards IRONMAN® Pro Series standings, a $50,000 USD event total pro prize purse, and two slots per gender for the 2026 IRONMAN 70.3 World Championship triathlon in Nice, France.
The event can be viewed live in person and will be broadcast across multiple platforms for viewers around the world, including proseries.ironman.com, Outside TV in the US and Canada, DAZN, L’Equipe in France, and ESPN (within Disney+) in Latin American and the Caribbean meaning that triathlon fans from all over the world will be able to experience the stunning Swansea course.
Highlighting a top caliber women’s field will be 2024 IRONMAN Pro Series Champion Kat Matthews (GBR). Matthews, who has had a stellar start to her season with a stunning set of results at the Memorial Hermann IRONMAN Texas North American Championship and the Qatar Airways IRONMAN Hamburg European Championship races, currently sits in second position in the Series and will be on the hunt for points to push into the lead. Looking to retain her overall lead in this year’s Series will be Germany’s Anne Reischmann, whose victory at the ISUZU IRONMAN South Africa African Championship race positioned her as an early season threat. Wearing bib number one and looking to defend her title in Swansea will be Nikki Bartlett (GBR), who was also the fifth-place finisher at the 2024 IRONMAN World Championship® triathlon in Nice.
In the men’s field, bib number one will belong to defending champion Harry Palmer (GBR), whose win last year was followed by a respectable eighth place finish at the 2024 IRONMAN 70.3 World Championship race in Taupō. Palmer will have his work cut out for him, however, as also heading to Swansea is two-time IRONMAN World Championship podium finisher and 2025 IRONMAN African Champion, Magnus Ditlev (DNK). Coming off the back of an eighth-place finish at the Mainova IRONMAN Frankfurt European Championship triathlon this past weekend, competitors will no doubt be hoping Ditlev’s legs are still feeling the effects.

The IRONMAN 70.3 Swansea swim course begins at the Prince of Wales Dock kicking-off with a 1.2-mile swim through Swansea Bay. Once out of the water, athletes will head out onto the 56-mile bike course that passes through the seaside village of Mumbles along roads that hug the Gower’s coastal clifftops before cycling out through the rural Welsh countryside and heading back into the city. The event will cap off with a 13.1-mile two loop run course which takes them from the city centre, out past the new eye-catching gold-colored Swansea Arena, towards Mumbles before heading back towards the finish line at the Marina.
In addition to the professional field, 2,500 registered participants will compete at IRONMAN 70.3 Swansea triathlon on the same course, looking to earn age-group qualifying slots to the 2026 IRONMAN 70.3 World Championship triathlon taking place in Nice, France.
