Start from Weir Wood (Layhams Lane). 20 mile route takes about 1hr 40mins to ride. 80% off road trails, single track and paths. Additional loop can be added from Jackass Lane up to Keston via some really good stairs. The North Downs Way is a bit rubbish, so I started on it but then turned back and road across the Warlingham and into more bridle ways I knew. Map of ride here: http://connect.gar
