THE MOST SCENIC RUNNING EVENT IN CAMBRIDGESHIRE!

You are invited to the beautiful Grafham Water to tackle a scenic 10 mile trail run that circumnavigates the reservoir. The route starts on the iconic dam, ensuring a rapid start, before taking you around the fast running, scenic trails surrounding Grafham Water, through the Woodland Nature Reserve, past Dragonfly Pond and around Sanctuary Bay before finishing with the last mile along the length of the dam wall.

CANICROSS - we dont want our furry friends to miss out! You can take part with your dog as long as you follow these Canicross guidelines using a recognised dog harness, and please keep dogs on their leads at all times. The Canicross will be started in a separate wave before the runners for safety reasons and to avoid any trip hazards. There will be dog bowls at the water stations and dog treats at the finish line.

We are delighted to let you know that Grafham Water Centre are offering camping the night before our event. Take the stress out of getting to the event on time by booking your camping HERE

Charity - Join us in making every stride count by raising money for our partner charity, Alzheimers Research UK - your run will not only challenge your limits but also change lives, one step at a time, for a cure. Opportunities to donate and fundraise will appear at checkout.
