The beautiful multi-terrain course gently undulates its way through the spectacular parkland, woodlands and lakeside setting of the breath-taking Grafham Water Nature Reserve.

Each Lap is just over 14km and is broken up into two sections, both of which have an event village containing feed stations and medical facilities.

Each section has two water stations giving four in total on each lap. You can tackle the full lap or break it up, taking a rest at each event village
