The flat, fast-paced Cardiff Half Marathon route passes the city’s most breath-taking scenery and iconic landmarks. Along the way, enjoy sights like Cardiff Castle, Principality Stadium, Civic Centre, and the stunning Cardiff Bay.
I absolutely love the Cardiff Half Marathon route. It's definitely one of the most scenic that I've 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!
