Our 50km route starts from the Shuttleworth Estate following a cross country route on private trails.
Runners then complete an anti-clockwise loop passing through Old Warden, Haynes, Clophill, Chicksands, Shefford and Broom.
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.
