The Time Trial is one of two Road Cycling events and will be contested individually against the clock over a distance of 44km for men and 29km for women. Riders set off at 90-second intervals and the rider with the quickest time of the day is the winner. The races will happen on day 5 of the Olympic Games on 1 August 2012. They will start on the driveway to Hampton Court Palace and finish outside the Palace grounds on Hampton Court Road.
Each race is contested over a single lap which is slightly different for men and women, reflecting the respective distances. The course goes through the London Borough of Richmond, the Royal Borough of Kingston upon Thames, Surrey, and Elmbridge Borough.
The Time Trial is a free event for spectators and will not be ticketed.
