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 will be cheered on by the crowds, come rain or shine! This course is predominately flat, so it's a great race for newcomers, or if you're going for a personal best.
