2022 Eden Project Marathon and Half Marathon

Race Features

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.

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

One tree for the Queens Jubilee will be planted for each runner registered.

Hundreds of T-shirts are either not collected or not worn after race events each year so we have taken the decision not to offer a T-shirt at this years event and instead, will plant a tree sapling at the Eden Project for every runner registered to support the Queens Jubilee.

• Pasty and a beer for all race runners – where else but Cornwall?

• 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

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.

Please check our page regularly for the latest information relating to the pandemic, as we will be updating in line with government guidelines.

Are there cut-off times for the Marathon?

We have a strict cut-off time for the Marathon of five and a half hours. We have also set up interim cut-off times to ensure that runners make it around the course in a safe and timely way.

If you do not reach the seven-mile mark within one and a half hours you will be diverted to the Half Marathon course. You will receive a Half Marathon medal and t-shirt at the finish but will not be eligible for category positions in the Half Marathon.

If you do not reach the mile 13 (Lanlivery) within two hours 55 minutes, and mile 17 (Luxulyan) within three hours 30 minutes, you will not be allowed to complete the course and will be transported back to Eden. You will not be eligible for a medal but you will of course receive your t-shirt, pasty and pint.

There is no cut-off for the Half Marathon.
