The Route

Chobham: 178km, 2354m

The ride starts on quiet Surrey lanes before turning onto Staples Lane with views over London. After a quick descent we head south into Sussex for 45km of relatively quick rolling terrain. At 71km we hit Ditchling Beacon – 1.5km at almost 10% before descending into Brighton for our second feed stop by the sea.

From the coast we have a 10km false flat / gentle climb and a lumpy 40km to get back to the Surrey Hills where two last climbs await – Leith Hill, the highest point of the route & we save the steepest climb for last, the wicked White Down just 10km from the finish. Over 2,000m on this London – Brighton – London route with some of the best riding in Southern England.
