Cycling outcast Lance Armstrong has said he would take banned substances again if faced with the same circumstances that saw him dope in 1995. The American said it was not possible to win cleanly when he was dominating the Tour de France with a record seven wins from 1999 to 2005 but that the race could now be won by a 'clean' rider. Armstrong was stripped of his Tour titles and given a life-ban from cycling by the United States Anti-Doping Agency (USADA) in 2012, having denied for years he was a drugs cheat. The cancer-survivor eventually made a public confession in a television interview with US chat show host Oprah Winfrey in 2013.
