About

The Chiltern Hills 100K is a 100 km ultra marathon from Runaway Racing, starting from Chesham at 7am on 2 October 2027 and taking in some of the finest spots in the Chiltern Hills. This anticlockwise 100-kilometre loop follows a carefully planned route that showcases the area's natural beauty and landmarks.

It is a true test of endurance, with technical terrain, rolling hills, sweeping views throughout and 1,800 metres of elevation gain. Runners pass through the Ashridge Estate, climb to the top of Ivinghoe Beacon and continue via Coombe Hill, Whiteleaf, Bledlow Ridge and Great Hampden, supported by well-stocked checkpoints and expert organisation. Designed for British and international athletes looking for a rugged yet scenic ultra, it is set to become a fixture on the trail calendar.
