North Downs Way 100

The North Downs Way 100 is presented as a 100 mile continuous trail event that follows the North Downs Way footpath from Farnham in the Surrey Hills to Ashford in Kent. The course distance is listed as 103 miles with a total ascent of 11,000 ft. The event is held under a UK Athletics Permit through the TRA, and also serves as a Western States qualifier. This edition is the 16th annual running and the race date is 8 Aug 2026.

About 80% of the route is trail and 20% road, with many trail sections, steep climbs and staircases. The course is marked by national trail posts and additional tape and arrows, but runners are ultimately responsible for navigation. There are road crossings that are not marshalled. Trail shoes are advised and mandatory kit checks are enforced; required equipment includes a charged mobile phone, at least 1 litre of carrying capacity for fluids, a survival blanket, waterproof jacket, whistle, headtorch and backup light, a dry long sleeve layer, and a cup.

Runners must meet a qualifying standard of at least one 50 mile finish within 15 hours in the specified qualifying window, and the overall finish cut off is 30 hours. The event lists 12 fully stocked aid stations with options for vegetarian, vegan and gluten free needs, hot drinks and hot food available at later stations, drop bag provisions and specific locations, pacer and crew rules, and a range of finishing awards including timed buckles and veteran category prizes.
