About this event

Dark Downs 50k takes runners through the rolling chalk hills of the South Downs, one of England's most scenic national parks. Three distances cater to different ambitions: 34 kilometres for those stepping up in distance, the 50-kilometre namesake route, and a formidable 161-kilometre ultramarathon that traverses nearly the entire South Downs Way. Starting from Plumpton, the courses wind through ancient woodland, open downland and historic villages. The longer distances demand strong night navigation skills and mental resilience as darkness falls over the Downs. The chalky terrain provides excellent grip even in wet conditions, though the cumulative elevation — 3,640 metres on the longest route — makes these seemingly gentle hills a serious endurance challenge reserved for experienced runners.
