Cardiff Half Marathon
Cardiff CF10 3RB, UK. Sunday, 4th October, 2026.
Whether you want the challenge of a 10k run, your first half marathon, or the full 26.2 miles, there’s sure to be an event near you. Whilst you’re getting fit, you’re also helping our work to save nature.

We have allocated places at the below events, so pick the race that works for you, sign up to support the RSPB, and get training! As you’ll be raising money to help our work to save nature, we’ll give you your own RSPB shirt to race in, too.
If you already have a ballot place at a race and would like to use it to raise funds for the RSPB, please reach out to us at communityfundraising@rspb.org.uk and we’ll help you along the way.
It would mean the world to have your support as we work to help birds, other wildlife and habitats to thrive.
