70,000 cyclists have begun registering for Ride London, a family bike ride around the capital's tourist landmarks in August.
London's Mayor Boris Johnson and Olympic gold medallist Laura Trott announced the route for both the fun event on August 3rd and a 100 mile road race featuring world class elite cyclists and amateurs the following day.
Claiming that the cycle was invented in London 200 years ago, the Mayor revealed at the launch that he will ride the main event himself along with 20,000 fellow cyclists.
Up to a quarter of a million spectators may line the route generating millions of pounds for the London economy.
