Cardiff Half Marathon

Brecon Carreg Cardiff Bay Run

Set in the heart of Cardiff’s historic Bay, the Brecon Carreg Cardiff Bay Run is a fast, flat and friendly event for all ages and abilities. Previously known as the Cardiff Bay 5 Mile, the race returned in 2017 with a little makeover and stunning new 10km course. It attracts a sell-out 6500 runners year on year.

The route takes in all of Cardiff Bay’s most iconic landmarks, starting and finish in Roald Dahl Plass, passing the Wales Millennium Centre, Mermaid Quay, the Pierhead Building, Senedd, Porth Teigr and the Cardiff Bay Barrage.
