Boris Johnson and actress and model Kelly Brook have taken part in a photo call this morning to raise awareness of London's forthcoming Skyride.
The Mayor of London's Skyride is set to take place on Sunday September 20th in the centre of the capital. The ride is part of a series of mass participation cycle rides across Britain.
Traffic will be banished from some of London's most famous streets for the ride, which is hoped will draw cyclists of all ages and abilities.
