The director of the Tour de France said that holding the race stages in Britain had been "beyond our wildest expectations."
Christian Prudhomme said: "It was perfect. It was unbelievable," adding that huge crowds had lined the streets on the 30 km (18 miles) of road that the race took through Greater London.
He added the Tour de France would definitely come back to Britain at some stage.
