Mountain Biking on the North Downs [PDF ebook] 

This guidebook covers 20 mountain biking routes set throughout the length and breadth of the North Downs, from Farnham in the west to Dover in the east, as well as a route along the Downs Link, which joins the North Downs Way with the South Downs Way. They range from 18.5km to 59km in length and up to 90% off road. The routes, illustrated with OS map extracts and height profiles, are graded for difficulty (blue, red and black) and are suitable for mountain bikers with at least some experience and a reasonable degree of fitness. The guide gives practical information on recommended gear, preparation and safety, as well as details of accommodation and local bike shops.
