North Downs 50 Ultra Challenge

The North Downs 50 is a looped trail event based at a Guildford basecamp at Loseley Park on Sat 31 July 2027. The route runs along the North Downs Way and through the Surrey Hills area of outstanding natural beauty, crossing chalk ridges, ancient woodlands and viewpoints including Chantry Woods, St Martha's Hill and Newlands Corner.

Multiple distance options run from the same basecamp and follow signed routes with GPS tracking and an event app that provides maps, training guides and on-the-day information. The organiser provides covered rest stops roughly every 12.5 km, regular snack stops, meals about every 25 km, hot and cold drinks, medical and massage teams, baggage services and a timing system that logs progress at rest stops.

Facilities and services at the basecamp include camping on Friday and Saturday nights, parking, shuttle transfers to Guildford train station and bookable extra meals. Finish-line services include a finisher's medal, t shirt, a glass of fizz and a hot finishers meal. An Ultra March category and a Trailblazerz running category are available for participants who wish to follow specific pacing or competitive options.

Distances and approximate ascent figures are published for each option and some routes offer an optional bus transfer from offsite finishes back to the basecamp. Visit the organization's website for the most recent information.
