Route Description

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.

CP 1 - Haynes Village Hall
CP 2 - Shefford
CP 3 - Broom Village Hall
