Cardiff Half Marathon 2021

Runners completing the Cardiff Half Marathon

Join Dogs Trust and 25,000 runners at the UK's second largest half marathon in Cardiff!

Run the Cardiff Half Marathon with Dogs Trust and take in some of the capital’s most iconic landmarks, whilst raising funds to help our furry friends. Starting at Cardiff Castle, you’ll pass the Cardiff City Stadium and Millennium Centre, as well as stunning scenery and historic landmarks, such as the beautiful Roath Park Lake and Penarth Marina.

The race draws huge crowds of spectators, creating an unbeatable atmosphere and the predominantly flat and fast course makes it ideal for both first time runners and those looking to set a personal best!
