Route information
The race starts outside Cardiff Castle and runners then head down past the Principality and Cardiff City Stadiums on the way to Penarth. They take in the glorious Penarth Marina before crossing the barrage and heading to Cardiff Bay. Runners run right through the heart of the bay taking in the Norwegian Church and Wales Millennium Centre.
The course then heads towards the north of the city and runners will complete a loop of the beautiful Roath Park Lake before the grandstand finish in the heart of the city at the Civic Centre.
The predominantly flat and fast course makes it ideal for beginners and elites.
