Supporting Cancer Research UK
The Llangollen Round was created with a single overriding purpose: to celebrate the beauty of our Welsh hills while raising critical funds for Cancer Research UK.
Over the last 15 years, the Llangollen Round Challenge and associated guidebook sales have raised more than £400,000 for the charity, including a record-breaking £161,000+ during the 2025 triennial challenge event alone.

Their history reaches back over a century, and they are now the world’s leading independent charity dedicated to saving lives through research.Key Facts
