The London–Surrey Cycle Classic was a one-off, one-day bicycle race that served as one of three U.K. events in the year-long 2010–11 UCI Europe Tour and acted as the test event for the 2012 Summer Olympics. The race was part of the London Prepares series of events. The race was run over most of the Olympic course, starting in the Mall and heading into Surrey, where the riders completed two laps of the Box Hill loop before making their way back to the Mall. The course took the riders through or beside four Royal Parks and six London Boroughs. Most of the riders represented countries instead of trade teams; however, there were several, mainly British, trade teams in the race with England being classified as one of them. The race was won by 2011 Tour de France Green Jersey winner Mark Cavendish.

London Prepares series is the banner under which the test events for the 2012 Summer Olympic and Paralympic Games were held. The events which make up the series took place in 2011 and 2012.
