Mark Cavendish on doping, swearing and Olympic gold

An in-depth interview with Tour de France green jersey winner Mark Cavendish, who became the first Briton to win the jersey for the race's best sprinter.

Cavendish talks to BBC Sport's Jonathan Legard about his passion for the Tour, how he recuperates after an exhausting stage and passionately defends cycling's image.

He says he will always wear his heart on his sleeve, even though he is trying not to swear on Twitter, and has targeted defending the green jersey and winning Olympic gold at London 2012.
