With world-renowned spectator support and epic courses, this is the race that legends are made of.

Hosted in the charming Welsh seaside village of Tenby, Pembrokeshire, athletes leave as friends in this unique, inviting and truly special destination nicknamed the "Iron Town".  IRONMAN Wales sees Tenby come alive to a stunning sunrise swim on Tenby's sandy North Beach, wild bike course scenery along Pembrokeshire coastline, and a fan-filled town-centre run in Tenby.

The 2023 race offers qualifying slots for the 2024 VinFast IRONMAN World Championship in Kailua-Kona, Hawai'i.
