For 2026 the Cardiff Half Marathon is operating a ballot system for people to get places to run if they’re not signing up through charity partners like us at the link above. If you've secured your own place through the ballot then we'd love to welcome you to our team. There's no set fundraising target, we just ask that you raise what you can to help us stop people dying of bowel cancer. Click on the link below to join our team today.
