Cardiff 2024 Sprint

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 takes in 2 laps of a 9k course. Heading out of transition under the shadow of the Wales Millenium Centre you will head along James Street and down Ferry Road. You will turn around at the Morrisons Supermarket roundabout and fly back up the road the way you came. You will then head up Lloyd George Avenue and thrill at the speed on this section, with another turn around to come at the top so that you get to fly down the avenue once again. The lap ends at the entrance to the Oval Basin where once again you’ll be under the watchful eye of the Wales Millenium Centre. Unless of course you have another lap to go! This route is on ENTIRELY CLOSED ROADS.

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 Millenium Centre, the Senedd so you’ll have plenty to keep you motivated as you go for your PB!
