Take part in Wales’s largest mass participation event by running the Cardiff Half Marathon.

The flat, fast-paced route of the Cardiff Half Marathon passes the city’s most breath-taking scenery and iconic landmarks including Cardiff Castle, Principality Stadium, Civic Centre, and the stunning Cardiff Bay.

I absolutely love the route that the Cardiff Half Marathon follows, it is definitely one of the most scenic that I have run. I have 10+ half marathons so far and this year it was the best supported one. Thank to you all at Action for Children for all of the support. I will be back again next year!
