Located in the iconic Cardiff Bay, this triathlon is one of the most unforgettable city races on the calendar! You'll be part of an elite group who have swum in the world famous bay, this is followed by a fantastic, fast cycle route along completely closed roads. The triathlon is rounded off with a spectacular run along the Cardiff Bay barrage. The event village and transition (one of the most beautiful and striking in the sport) will be held on Roald Dahl Plass in front of the Wales Millennium Centre.

With Olympic, Sprint and Mini Sprint distances available, there's something for every ability at the Cardiff Triathlon!
