VIDEO: Lance Armstrong's ‘I’m clean’ Nike video


Keeping a poker-face in this Nike advertisement, Lance Armstrong undergoes a drugs test and answers the prompt "what are you on?" with the inspirational, macho, and now widely discredited slogan: "I'm on my bike, busting my ass six hours a day". 

Armstrong has been stripped of his seven Tour de France titles and banned from cycling for life, after the International Cycling Union (UCI) upheld the United States Anti-Doping Agency's allegations that Armstrong ran "the most sophisticated doping programme sport has ever seen".
