On this 13.1 mile course, you'll pass all of the city's most breath-taking scenery and iconic landmarks, including Cardiff Castle, the Principality Stadium, Civic Centre and stunning Cardiff Bay. This is a flat route so you have the chance to achieve a personal best! Spectators will also line the streets to cheer you on, creating a buzzing atmosphere.
Charity Place
To register for one of our limited charity places in the Cardiff Half Marathon, you will be required to pay a £10 registration fee and commit to raising a minimum sponsorship target (not including gift aid) of £250.
Own Place
If you have secured your own place through the Cardiff Half Marathon organisers directly, we would love for you to join #TeamStroke. Those who secure their own place will have no minimum sponsorship target, but everything you do raise will help rebuild lives after stroke.
