Route details

The race begins, and ends, on the Hampton Estate, just outside Seale, and travels along the North Downs Way as far as Moor Park (close to the edge of Farnham). The route then heads south to Tilford and crosses Hankley Common before a long climb up to the Devil’s Punchbowl on the edge of Hindhead. Having skirted the edge of the Punchbowl, the route drops under the A3 before climbing to Bowlhead Green; from there the route passes through Hambledon and the edge of Hascombe before crossing the Wintershall Estate and turning north along the Downs Link to Bramley. Having passed around the north of Chinthurst Hill, the route climbs up to Blackheath before dropping down to the Tilling Bourne next to the old gunpowder mills before the steepest climb of the route from Chilworth Manor to the top of St Martha’s Hill. From St Martha’s the route leads back along the North Downs Way, passing through the edge of Guildford and crossing the Loseley Estate before reaching Puttenham. The finish is reached after a final climb to the top of Puttenham Common.
