Other 10K events
At present the Brecon Carreg Cardiff Bay 10K cannot be included in the series. Discussions are ongoing with Cardiff City Council around the feasibility of a 10K route in Cardiff Bay whilst development work takes place in preparation for a new indoor arena and tram line. We hope to see a return for this popular event soon!
