This two day festival of cycling takes place in the newly opened Queen Elizabeth Olympic Park, opened just last month on the north section of the former Olympic Park. First up, Saturday's 'FreeCycle' welcomes 70,000 cyclists to ride along an eight mile, traffic-free loop in central London. Britain's biggest bike festival culminates with Sunday's 'RideLondon 100' - a 100 mile race for amateurs that organisers have described as the London Marathon on wheels. Other Sunday events include the 'RideLondon Grand Prix' - a series of criterium-style races through central London for professional women, junior riders and hand-cyclists - and the 'RideLondon Classic' - the biggest ever men's professional one day race in Britain. Both the Classic and 100 races will start at the Olympic Park and cover a similar route to that used in the London 2012 Olympics - taking in all eight London boroughs, Richmond Park and the Surrey countryside, before finishing on The Mall. Ride on!
