Event information
Join us for the Chiltern 50 Challenge. Our route follows the Thames to Henley Bridge, then out into countryside on Shakespeare’s Way, Icknield Way, and Chiltern Way with rest stops enroute. The full 50 km route, with over 900 metres of climb, is a loop starting and finishing at our basecamp at Henley Showground – with a halfway at Lewknor. If 25 km is more your thing – you can do a loop from the basecamp.
The Henley basecamp has Friday & Saturday evening camping options (+ showers). We’ll have a celebration BBQ, bar & entertainment evening after the tough day out on the trails!
