About This Route
The Cardiff Half is Wales' biggest mass-participation event: 27,500 runners on a course that shows off the capital — starting beneath the castle walls, sweeping past the Principality Stadium, around Cardiff Bay and across the barrage, through Penarth and back past the Senedd to finish in the civic heart of the city.
Our 3D printed terrain model traces the full 13.1 miles over the landscape of Cardiff and the bay. Add your name and finishing time and it becomes a permanent piece of the day — a Welsh race remembered in relief.
