There's no date for the next edition of Greensand Country 50K yet. If it comes back, newsletter subscribers will hear first.

A stunning single loop 50K ultra marathon around the Greensand Country trails in Bedfordshire.

Our trail route follows a unique loop though a series of attractive countryside villages and the trails that connect them.

This race is a great choice for those looking to post a faster 50K time, or if you want to avoid the bigger hills encountered on our Chiltern ultra events.

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.
