The route covers about 50.3 km with over 800 m of ascent and follows established trails through Berkhamsted Common, the National Trust Ashridge Estate and significant sections of The Ridgeway National Trail.
There are three full checkpoints at Aldbury (18.4 km), Boswells Farm Wendover (31.6 km) and Wigginton Village Hall (42.2 km), plus a water only point at Beacon Road (9.3 km). Checkpoints provide water, electrolyte drinks, gels and chews, a selection of snacks and fresh fruit, and sandwiches at the later stops.
