A firm fixture in the running calendar, the Eden Project Marathon and Half Marathon offers hilly multi-terrain courses around the famous site, following a challenging route through areas of spectacular mining heritage and beautiful countryside landscapes.

Cornwall’s biggest running event returns on Sunday 11 October 2020, with a multi-terrain route through spectacular countryside.

We created the course through Cornwall’s dramatic Clay Country not only to offer a unique sporting experience for runners nationwide, but to showcase the unique region on our doorstep. The idea came from a conversation with the local St Austell Running Club, whose commitment, enthusiasm and passion have been invaluable in putting on the event.

The Marathon is just one of the many ways Eden aims to act as a catalyst for economic growth in the local region. If we could build this place, in a former clay pit, surely together we can all take on even bigger challenges…
