The Cardiff Half Marathon is one of the UK’s largest road races, taking runners on a 13.1 mile journey through the heart of the Welsh capital. Starting on Castle Street outside Cardiff Castle, the closed road course showcases many of Cardiff’s best known landmarks before finishing in the Civic Centre.
Runners follow a predominantly flat and fast course past the Principality Stadium and Cardiff City Stadium before heading through Penarth, across Cardiff Bay Barrage and into Cardiff Bay. The route then heads towards Roath Park Lake before returning to the city centre, making it well suited to first time half marathon runners and those chasing faster times.
The race is known for its large field and strong spectator support, with entertainment and live music adding atmosphere around the course. Feed stations and pacers support runners along the route, while chip timing records performances from start to finish. The Cardiff Half Marathon also forms part of the international SuperHalfs series.
