Cardiff 2025 Sprint Duathlon

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. Two spectacular runs along the Cardiff Bay barrage sandwich a fantastic, fast cycle route along completely closed roads. 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.

Route Description

Both of the Duathlon runs are fast out and back routes, showing off the sights of Cardiff Bay along the way. For Run 1, start underneath the finish arch and head out towards the Norwegian church and along the cycle path, taking in the sites of industrial heritage that Cardiff is so renowned for. Then reach the turn around point and race back the way you came into transition ready for the Bike section.

The Bike course is 2 laps of a 10k laps flat and fast course on ENTIRELY CLOSED ROADS. Heading out of transition under the shadow of the Wales Millenium Centre you will head along James Street and down Ferry Road. Taking in the sites of the Cardiff International Sports Village and along the side of the Ely you will reach the first turn around point. Flow back in the direction you’ve come, with views of the Millenium Centre, the Senedd and of course the iconic Cardiff Bay. The lap ends at the entrance to the oval basin beneath the Wales Millennium Centre.

Run 2 takes you out of transition, and head in the same direction as Run 1 but this time you go right up to the Barrage before you turn around. On your way back you get the iconic views of the Pierhead Building, the Wales Millennium Centre, the Senedd so you’ll have plenty to keep you motivated as you go for your PB!
