The US Anti-Doping Agency said Thursday it would ban cyclist Lance Armstrong for life and strip him of his Tour de France wins.
Armstrong on Thursday night dropped any further challenges to USADA’s allegations that he took performance-enhancing drugs.
Armstrong had an unprecedented winning streak at the Tour de France, taking the title from 1999 to 2005.
