Hundred Hills 50K



All ages

  • 50 km trail running


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 event. With a 9 hour cut off the race is ideal for runners looking to take on their first ultra and 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 take in 4000ft of climb, visiting picturesque villages and ancient woodland while traversing some incredible trails. Back at Stonor there is the opportunity for friends and family to spectate, food and drink on site and is a fabulous day out for all. As with all Centurion events, runners will be fully supported by 5 well stocked aid stations, full medical support and a marked course. Race held under full UK Athletics Permit granted through the TRA (Permit Number Pending).
