Why you'll love taking part

Here are just a few reasons why we think you’ll love the event: 

  • All runners get a pasty and a beer at the finish line – where else but Cornwall?!

  • All finishers get a themed medal to take home

  • Entrants and accompanying family, friends and supporters receive free entry to the Eden Project on the day

  • There'll be water stations every three miles and isotonic drinks every seven miles to fuel up!

  • Chip timing and free online analysis of your race will be available post-event via RunPix

  • There are cash prizes for race winners and prizes for category winners

  • You'll be supporting the creation of wildflower habitats here at Eden to help wildlife and pollinators thrive. This is our alternative to providing race t-shirts, as hundreds of them are not collected or not worn after events every year nationwide. If you would still like a souvenir t-shirt, hoodie or tote bag, you can purchase through our sustainable, print-on-demand partners.

Fantastic scenery, great organisation, where else do you get a pint and a pasty!

Marathon

Why we set up this Marathon

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…
