Brecon Carreg Cardiff Bay 10K is a spring road race around Cardiff's historic Bay, and it is the largest 10K road race in Wales. The course is flat and fast, so it suits runners chasing a quick time as well as people trying the distance for the first time.
The route passes some of the Bay's most familiar landmarks, including the Wales Millennium Centre, the Cardiff Bay Barrage, and the Norwegian Church. The field includes some of the UK's top athletes, but the event also makes room for charity runners, fitness runners, families, and children through its supporting Junior races.
