The Hundred Hills 50km is a beautiful and challenging 50km trail ultra through the heart of the Chiltern countryside. Our season opener for 2024, the race consists of two different 25km loops. It starts and finishes at 850 year old Stonor Park, providing a truly stunning backdrop to the race. With a 9 hour cut off the race is ideal for those looking to take on their first ultra, those looking to take a step up to our longer events, but also for those looking to race fast, early in the year. The route takes in 4000ft of climb, visiting picturesque villages and ancient woodland while traversing some incredible trails. As with all Centurion events, runners will be fully supported by 5 well stocked aid stations, full medical support and a marked course. Back at Stonor there is the opportunity for friends and family to spectate, coffee to be drunk and street food to be eaten!
