Lance Armstrong has decided not to enter arbitration with the U.S. Anti-doping Agency over allegations the champion cyclist used performance enhancing drugs during his career.
The decision comes after a federal judge threw out Armstrong's lawsuit Monday (8/20) to block the drug agency's case from moving forward.
Armstrong's run of seven consecutive Tour de France wins was historic, but it may no longer be in the record books. The U.S. Anti-Doping Agency says it will strip Armstrong of his titles and ban him from cycling for life.
The decision comes after Armstrong announced he is giving up the fight to clear his name. "There comes a point in every man's life when he has to say enough is enough. For me, that time is now," Armstrong said.
The doping agency accused Armstrong of using banned substances including EPO, Testosterone, Corticosteroids, and masking agents.
The head of the USADA told Reuters: "This is a heartbreaking example of how the win-at-all costs culture of sport, if left unchecked, will overtake fair, safe and honest competition."
The latest challenge to Armstrong's legitimacy started in June when the agency announced it had lined up 10 former Armstrong teammates who were willing to testify that the Texan cheated.
In an interview with 60 Minutes, former teammate Tyler Hamilton told Scott Pelley, "I saw it in his refrigerator. I saw him inject it, more than one time."
Armstrong denies the claims, saying, "I know who won those seven tours, my teammates know who won those seven tours, and everyone I competed against knows who won those seven tours. Nobody can ever change that."
Cycling's governing body, the International Cycling Union, says it will make a decision Friday (8/24) on whether to appeal Armstrong's suspension on his behalf. It has backed Armstrong's claims that the USADA does not have authority to strip Armstrong of his titles.
