About the race
50K trail ultramarathon through the Chiltern Hills, held on 17 April 2027. The route follows Ridgeline trails and sections of the Ridgeway National Trail, starting from Berkhamsted Castle and finishing at Hampden Meadow in Wendover. The course passes Ashridge, Ivinghoe Beacon, Aldbury, Coombe Hill and Whiteleaf Hill and includes undulating terrain, ancient woodlands and rolling hills. The published elevation gain is 996m+ and the current route is slightly long at about 51 km due to local path closures.
