Route Description

Start your race with the exclusive opportunity to swim in Cardiff Bay. Cardiff Bay is supplied by two rivers to form a 500-acre (2.0 km2) freshwater lake around the former dockland area south of the City Centre.

Once through transition, you will head out on a 54 mile (88k) fast flat bike route, completing seven 12.5k laps of a 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. You will then head along Lloyd George Avenue and thrill at the speed on this section, before reaching another turn around to fly down the avenue once again. The lap ends at the entrance to the Oval Basin beneath the Wales Millenium Centre.

Your run is an out and back run route which you must complete five times, giving a great opportunity to catch all the sights along the way. Head out of transition first towards the Norwegian church and along the cycle path, taking in the sites of industrial heritage that Cardiff is so renowned for. The route is flat and fast especially as you run along the Barrage. The route back gives you views of the Pierhead Building, the Wales Millennium Centre, the Senedd and so much more that you’ll have plenty to keep you motivated as you go for your PB! The lap turn around is right by the Pierhead building, where you’ll double back and head out again to the Barrage. Once you get here a second time, it's time for your sprint finish; along Bute Place, around the corner, and into the finish line in front of the Wales Millennium Centre.
