Paris: Shamed US cyclist Lance Armstrong said in an interview with Le Monde on Friday, on the eve of the 100th edition of the Tour de France, that it was "impossible" to win the sport's most famous race without doping.
Asked whether it was possible to win without taking performance-enhancing drugs when he was riding, he responded: "That depends on the races that you wanted to win.
"The Tour de France? No. Impossible to win without doping because the Tour is an endurance event where oxygen is decisive," he was quoted as saying by the French daily.
