The route
Our 50km route starts from the Shuttleworth Estate following a cross country route on private trails.
Runners then complete an clockwise loop passing through Ickwell, Broom, Shefford, Haynes and Old Warden.
The terrain and surrounding countryside is varied, eyecatching and undulating throughout. This makes the course extremely runable and a great choice for anyone aiming to complete their first ultra.
There are three major checkpoints, at 16km, 28km and 41km. Additional water points will be added if it is a particularly warm day.
