This ride to coffee and cake is definitely a route of two halves.
Climbing Beech Avenue and Critten Lane to cross the downs and descending White Down (caution!). Then its another long easy climb to Holmbury St Mary and descent to Forest Green. Cross the A29 and A24 to reach Newdigate.
The farm shop is on the Rusper Road south of Newdigate.
The return leg is shorter and flatter via Leatherhead.
