Armstrong: My success was one big lie

Lance Armstrong has confessed to using performance-enhancing drugs during all seven of his Tour de France victories, saying: "I view this situation as one big lie."

After years of denials, the 41-year-old American told Oprah Winfrey in a much-anticipated television interview that during his record run, from 1999 to 2005, he used blood-boosting agent EPO, blood doping, testosterone, cortisone and human growth hormone.
