Cardiff Duathlon 2021

The Cardiff Duathlon is the perfect option for competitors who want to experience the cosmopolitan atmosphere of the Cardiff Triathlon without getting their feet wet.

Brand new for 2021, the Sprint Duathlon features all of the incredible sights that Cardiff Bay has to offer allowing athletes to experience the rapturous welcome home in the shadow of the Millennium Centre.

Signing up the Cardiff Duathlon is your ticket to compete in one of the UK's finest city duathlons. Not only should you expect a completely closed road route and coverage that is beamed across the world, but you should also expect a race that you want to share with everyone.
