2. IN THE CLEAR

A month later, in August 2005, the French paper L'Equipe reports that six of Armstrong's urine samples from 1999 came back positive for the endurance-boosting hormone EPO when retested in 2004, prompting an investigation by France's World Anti-Doping Agency. "Absolutely not. Never, not once," he says in a 2006 interview with NBC's Ann Curry after being asked if he had ever doped – and the International Cycling Union agrees, exonerating him completely. Three years later, Armstrong returns to the Tour de France, placing third.
