Leipheimer speaks at USADA symposium

During long training rides with his friends and foes, Levi Leipheimer would trade secrets with the other cyclists about what did and didn't work when it came to performance-enhancing drugs. One thing virtually all the riders agreed on: They wished they didn't have to dope, but felt they had no choice. Leipheimer, one of the key witnesses in the doping case against his former teammate, Lance Armstrong, was the headliner at a U.S. Anti-Doping Agency science symposium held over the weekend in Atlanta. The symposium was closed to the media. USADA CEO Travis Tygart told The Associated Press about Leipheimer's talk, which he said included the cyclist's discussion about ''the informal and formal consequences of doping and how that affects decision making.''
