Take on the Cardiff Half Marathon for DKMS

Sunday 5th October 2025

The race is extremely popular among those looking to run their first half, chase a PB or fundraise for charity. In fact, general entries sold out in 48 hours!

It is a flat, fast and scenic route around the Welsh capital with spectacular landmarks, live entertainment and supporter cheer points throughout the course. This is a race to remember, with many runners coming back time and again.
