Winter Downs 100

The Winter Downs 100 is a single-stage, point-to-point trail run covering 100 mi (160 km) with about 10,000 ft (3,050 m) of elevation. The route starts at Amberley Museum in the South Downs and follows a combined line of national trails: 42 miles west on the South Downs Way, then roughly 32 miles north-east via the Wayfarers Walk and St Swithuns Way to Farnham, and the final 26 miles along the North Downs Way to Juniper Hall at Box Hill. The course is identical to the second half of the Winter Downs 200.

Runners must complete the course within a 35 hour time limit. There are three aid stations on course offering hot meals and drop-bag access; runners may spend up to two hours at each checkpoint, and additional cut offs apply at each station. Crew are permitted only at designated points and are not allowed inside aid stations. Pacers are not permitted.

The course is not marked with event-specific signage; competitors must carry and use the official GPX files and familiarise themselves with the differing waymarks of the four trails. Live tracking and race medical coverage are provided throughout the event.

Entries are limited to an anticipated field of 100 starters and are subject to qualification review. The entry fee is £220 (£222 for unaffiliated entrants). Mandatory winter kit and spot checks are enforced, and specific equipment requirements include dual headtorches, waterproofs, a survival bag, a battery pack, and food and cash reserves.
