By taking part in this event, you will:

Participate in Cornwall's biggest running event.
Run through spectacular countryside.
Meet like-minded people.
Receive fundraising support.
Get a pasty and pint at the end of the race, along with a finishing medal and free entry to the Eden Project for you and your supporters!
Make a difference by creating a Cornwall where nature thrives.

We suggest that marathon runners aim to raise at least £500 and half marathon runners to raise at least £300.

A Cornwall where nature thrives can only become reality if we raise the funds needed to make it happen.

In fact, if you run the full marathon, the route goes right over Helman Tor at the top of our largest nature reserve. The reserve features a vast expanse of wetland at the heart of Cornwall and is home to wild beavers. (Please note: the Half Marathon does not follow the same route.)

Why run for Cornwall Wildlife Trust?

For Finn, this year's Eden Project Marathon is about more than the miles. He's taking on the challenge alongside his dad, Nick, continuing a family tradition of marathon running that stretches back generations. Inspired by his late grandfather Roger, an original London Marathon Ever Present member, Finn is using the run to support Cornwall Wildlife Trust and help protect the wildlife and wild places that future generations can enjoy.
