Armstrong return his medals and millions of dollars in prize money from those wins. Exactly how much will be determined later this week. Its the latest fallout from a u. S. Antidoping Agency Report released earlier this month that outlined overwhelming evidence that Lance Armstrong was a kingpin in a doping program. Nike, oakley, trek bikes, radio shack and anheuserbusch have all ended their relationship with armstrong, and last week the cancer survivor stepped down as the chair of his wildly successful livestrong foundation. He spoke at the charitys fundraising gala this weekend in austin. Its been a difficult couple of weeks for me, for my family, for my friends, for this foundation. I get asked a lot, people say, man, how are you doing . And i say, and i say this every time, and i mean it, i say, ive been better, but ive also been worse. Reporter armstrong has steadfastly denied using performance enhancing drugs and says he will continue to work closely with his cancer foundation. J
