Centurion North Downs Way 50
Farnham, United Kingdom • 16 May 2026
North Downs Way 50 is a 50-mile point-to-point ultramarathon along the North Downs Way National Trail, from Farnham, Surrey to Knockholt Pound on the outskirts of Greater London. With about 5,600 feet of elevation gain, the mostly off-road route traverses iconic chalk downs, including Box Hill, and links Puttenham, Guildford, Ranmore Common, Merstham and Oxted before finishing at Knockholt Pound. Now in its 15th edition, the race mirrors the first 50 miles of the NDW100 and constitutes the second leg of Centurion’s 50-Mile Grand Slam. Pacers and crews aren’t allowed; spectators may line the course away from checkpoints. Six fully stocked aid stations and a finisher medal complete the event.
