About the event

Take to the streets of Cardiff along with thousands of other runners in this iconic half marathon.

The route takes you round the buzzing city of Cardiff where you'll be cheered on by the crowds, come rain or shine! This course is predominantly flat, so it's a great race for newcomers, or if you're going for a personal best.


Secure your place today for £25 and a pledge to raise £350 for Breast Cancer Now.
