Join a mid-summer North Downs 50 Challenge! This looped route is set in an area of outstanding natural beauty of the Surrey Hills, taking in chalk ridges and ancient woodlands.
The 25km looped challenge sets out from Guildford early Saturday morning, along some of the most picturesque parts of the Surrey Hills Way – with a rest stop at half way with snacks and drinks.
Follow the North Downs Way to Dorking for a 24km challenge with fabulous views. You’ll get full support all the way, rest stops en route and a picnic lunch at the finish.
