Race features

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

  • Pasty and beer for all race runners – where else but Cornwall
  • Themed medal for all race finishers
  • Cash prizes for race winners and prizes for category winners
  • Free entry to Eden for runners and accompanying family members and supporters on the day
  • Water stations every three miles and isotonic drinks every seven miles
  • Chip timing, and free online analysis of your race via RunPix
  • One tree will be planted for each runner registered

We have taken the decision not to offer a t-shirt this year as thousands are either not collected or not worn after race events each year. Instead, will plant a tree sapling at Eden for every runner registered to support The Queen's Platinum Jubilee.

For more details:

If you would still like to purchase a souvenir t-shirt of the event, these will be available to purchase soon.

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…
