ance Armstrong will not be allowed to compete in the Ironman France triathlon later this month following new charges from the U.S. Anti-Doping Agency that he illegally doped when he competed in the Tour de France. While federal investigators closed a two-year investigation into doping allegations against the legendary cyclist in February without charging Armstrong, the U.S. Anti-Doping Agency continued to investigate. The department has threatened to strip Armstrong of his seven Tour de France titles. Armstrong responded to the charges with a statement, saying "I have never doped, and, unlike many of my accusers, I have competed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one."
