Castle 2 Castle 2026
20th September 2026 – Caerphilly to Cardiff, Wales
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 £151,000!
Want to be one of our Castle 2 Castle runners?
Make a difference with #TeamVelindre!
Every step our runners take through the small climbs of Caerphilly and the beautiful scenery of Cardiff raises vital funds for the Hospital of Hope, allowing us to continue making a difference to patients and families in Wales.

- Almost three complementary therapy sessions to aid with alleviating anxiety, cancer symptoms and treatment side effects for patients.

If all participants hit their £50 fundraising target, we will raise an additional £87,500. Collectively, this could directly support one of the 40+ clinical trials active at Velindre today or even fund up to 2 Clinical Nurse Specialists’ salaries for a year.
The importance of your fundraising is immeasurable.
