AUSTIN -
Lance Armstrong says it's over - and the U.S. Anti-Doping Agency agrees.
The U.S. Anti-Doping Agency says it will strip Armstrong of his unprecedented seven Tour de France titles after he declared he was finished fighting the drug charges that threaten his legacy as one of the greatest cyclists of all time.
Travis Tygart, USADA's chief executive, said Armstrong would also be hit with a lifetime ban on Friday.
Still to be heard from was the sport's governing body, the International Cycling Union, which had backed Armstrong's legal challenge to USADA's authority.
Armstrong says he will no longer fight the charges because he's tired of it. Says Armstrong: "There comes a point in every man's life when he has to say, "Enough is enough." For me, that time is now."
Armstrong called the USADA investigation an "unconstitutional witch hunt."
