The Cardiff Half Marathon is back!

The Cardiff Half Marathon is an event not to be missed. Not only is it the UK’s second-largest half marathon, it's Wales’ largest road race and largest multi-charity fundraising event. To top it off, it's also part of the Super Half Series, so be quick as it's like to sell out. Sign up now to secure your place! The route takes you past the city’s most iconic landmarks with beautiful scenery and historic buildings. The predominately flat and fast course makes it ideal for beginners and elites. The course then heads towards the north of the city and runners will complete a loop of the beautiful Roath Park Lake before the grandstand finish in the heart of the city at the Civic Centre. Already have a place? If you're lucky enough to secure your own place and would like to run for Marie Curie, please complete this form to confirm your place with us. We'll send out your running top and fundraising pack to welcome you to the team.
