Castle 2 Castle 2026

Join Velindre Cancer Charity for Castle 2 Castle 2026 and make strides towards Victory Over Cancer!

One of our most iconic #TeamVelindre events, Castle 2 Castle's 10.5-mile route takes place between two of South Wales's most stunningly scenic castles - Caerphilly to Cardiff. An event full of fun, community, togetherness, and dedication - it truly is a magical day in our event calendar.

Last year, we saw over 1,581 runners take part - smashing our previous record! And it was a record-breaking year across the board, as we also reached a staggering fundraising milestone of £150,000, 100% of which will directly support cancer patients and their families in Wales. Once registered, we ask all runners to raise a minimum sponsorship of £50.00, and more if you can, to help fund world class research and clinical trials, cutting edge treatments and vital support services including children's resources and counselling sessions for our patients.  

In association with the generous volunteers at Caerphilly Runners, this event wouldn't be possible without the support of our headline sponsors Peter's Foods and Castle Dairies. 

All runners must be 16+ to take part in this event.
