Centurion North Downs Way 50

North Downs Way 50

The North Downs Way 50 is a point to point 50 mile (81 km) race along the North Downs Way National Trail from Farnham in Surrey to Knockholt Pound on the outskirts of Greater London. The route covers approximately 5,600 ft (1,700 m) of climb and follows the first 50 miles of the NDW100, with about 80% on trail and 20% on road.

The event is limited to 300 starters and has a 13 hour time limit, with additional cut offs at intermediate aid stations. There are six fully stocked aid stations offering a range of nutrition and drinks with vegetarian, vegan and gluten free options, including gels, electrolyte drinks, water, soft drinks, fruit, snacks and sandwiches. Finishers receive a medal; prizes are awarded to the top three men and women and across veteran categories.

The course uses North Downs Way signposts carrying the acorn symbol, plus Centurion marker arrows and pink ribbons. There are several road crossings, some unmarked by marshals, so navigation and road safety are the responsibility of the runner. Pacers and crew support are not permitted; spectators are allowed but must avoid aid stations and checkpoints. A finish line bag (maximum 50 litres) can be deposited at registration and transported to the finish.

Entries open 21 June 2026 and include a qualification requirement of a completed marathon within event cut off times since 1 January 2021. Detailed maps and GPX files are provided by the organiser. Visit the organization's website for the most recent information.
