Lance Armstrong has announced he will stop fighting a barrage of drug charges from the US Anti-Doping Agency (USADA), putting at risk his unparalleled string of seven Tour de France titles and his legacy as one of the greatest sportsmen in history. Armstrong's declaration on Thursday night sets up a likely lifetime ban from the sport and the possibility that he will be stripped of his signature achievement the extraordinary run of Tour titles he won from 1999 to 2005.
