The Box Hill Gravel Loop features a moderate long anti-clockwise climb up through the woods to Box Hill.
The Ashdown Forest Loop is a long day in the saddle racking up well over 2000 metres of climbing. It is based on the Hell of the Ashdown sportive but with legs to and from London.
The Classic Surrey Hills (Long Version) cycling route is the other classic London Dynamo ride in the area. This one tackles five notable climbs. After the Staple Lane climb the route descends into Shere before climbing again up Peaslake Lane, and then Leith Hill. A fourth significant climb up to Ranmore Common is followed by the usual descent and Box Hill climb.
The Kentish Kraken winds its way across two ridges of the Downs (crossing the southern ridge four times!). Climbs include Crockham Hill, Brasted Chart (the steadier but longer north side of Toys Hill), and Ide Hill.
The London to Oxford one-way route heads out west from Kingston, shadowing the Thames, through Twyford and Henley and on into the Chilterns.
