Saying his "mythic, perfect story" was "one big lie," Lance Armstrong admitted that he cheated during most of his famed cycling career and that he bullied people who dared to tell the truth about it.

After denying doping allegations for more than a decade, he also said he used banned drugs or blood transfusions during all seven of his victories in the Tour de France.

"I will spend the rest of my life trying to earn back trust and apologize to people," Armstrong told talk-show host Oprah Winfrey in an interview that aired Thursday night.

Armstrong, 41, said he started taking performance-enhancing drugs in the mid-1990s and that his "cocktail" of choice was banned testosterone, EPO and blood transfusions using his own boosted blood.
