Course
A 100-mile point-to-point from Winchester to Eastbourne, opening with a four-mile loop of the Matterley Estate before joining the South Downs Way National Trail for its full length. The going is 85% trail and 15% road, much of it exposed chalk ridgeway with long sections of slippery chalk bed and rock that stay technical wet or dry. About 12,700 feet of climb, twelve well-stocked aid stations, first drop bag at mile 54, and a 30-hour limit. Finishes on the Eastbourne Sports Club athletics track.
