A 90Km ride with some steep climbs through the Chilterns, emerging into the sunshine after you descend towards the Oxford Vale from Stokenchurch.
Ride through the event feed station at the half-way point Ewelme; some riders take on too many cakes and biscuits and you'll soon be passing them as they struggle up the steeper second part of Swyncombe Hill. Cross the River Thames during a sprint through Sonning, and after a final long but gentle climb from Pinkneys Green to Quarry Wood, it's downhill to the finish, crossing the River Thames again at Marlow.
