Thousands of athletes and spectators are set to descend on Swansea this weekend as IRONMAN 70.3 returns to the city on Sunday 12 July.
Now in its fifth year, the event has become a firm favourite with competitors and residents alike, with this year’s race selling out quickly as participants prepare to travel from across the UK and beyond.
The race will once again feature as part of the global IRONMAN Pro Series, with professional triathletes competing for valuable points and the chance to be crowned IRONMAN Pro Series Champions.
Councillor Andrew Williams, Cabinet Member for Development at Swansea Council, said: “We’re thrilled to welcome back IRONMAN for another year. It’s an honour to be selected as one of only ten 70.3 races worldwide to join the Pro Series in 2026. We’re proud of our race and its stunning swim, bike and run course, which showcases the best of our local landscape on the world stage.
“The elevated Pro Series triathlon is worth £4.36m a year to local tourism and hospitality businesses as thousands of competitors and even more spectators travel to the city. We look forward to welcoming the athletes and their supporters to experience our city for another fantastic event.”
The race
IRONMAN 70.3 is a half distance triathlon made up of a 1.2 mile swim, a 56 mile bike ride and a 13.1 mile run.
The race begins with the swim at the Prince of Wales Dock before athletes head out on the bike course along the Gower coastline and through rural Swansea.
Competitors then return for the final run stage, following a double out and back route along Swansea Bay before finishing in Museum Park.
The run course was recognised as the third best in Europe, the Middle East and Africa at the 2025 IRONMAN Athletes’ Choice Awards.
Best places to watch
The IRONMAN 70.3 Expo opens at 11am on Friday 10 July and from 8am on Saturday 11 July.
Alongside athlete registration, visitors can browse official IRONMAN merchandise, visit sponsor stands, take part in activities, enjoy photo opportunities and create personalised spectator signs.
On race day, spectators can watch the swim from Prince of Wales Dock before heading to East Burrows Car Park to see athletes transition onto the bike course.
The finish line at Museum Park is expected to provide one of the biggest atmospheres of the day as competitors complete the event by crossing the iconic red and black finish carpet.
The weekend concludes with the Awards Ceremony and 70.3 World Championship Slot Allocation at the National Waterfront Museum.
