Chalfont Park gives runners the freedom to choose their distance on race day, completing as many 10.82K laps as they wish within the nine hour event window. Based at Chalfont St Peter Cricket Club, the course follows a scenic mix of public footpaths and woodland, with approximately 80% trail and 20% road.
Each completed lap counts as a finish, so runners can stop when they have reached the distance that suits them. Options range from a single 10K lap through Half Marathon, 32K and Marathon distances to 34 Mile and 41 Mile Ultras. With approximately 360ft of climbing per lap, the course provides a varied trail challenge while returning to the event base after every circuit.
An aid station is available on every lap with water, soft drinks and food, giving runners regular opportunities to refuel before heading out again. The event also includes a finisher’s medal for every completed distance, indoor bag drop, toilets, qualified medical support and free parking.
