Los Angeles - Lance Armstrong, banned from cycling for life after declining to fight charges leveled by the US Anti-Doping Agency, apparently will not be going quietly.
"Excited to be racing the #poweroffour tomorrow here in @AspenCO," Armstrong tweeted on Friday, hours after USADA said it was stripping Armstrong of his seven Tour de France titles and banning him from competition for life for multiple doping violations.
Armstrong had long denied doping accusations but on Thursday night said he was weary of the fight. He said he would not seek arbitration, triggering the sanctions by USADA.
"There comes a point in every man's life when he has to say 'enough is enough.' For me, that time is now," said Armstrong, adding he would have nothing further to say about doping.
Instead he waxed enthusiastic about the Power of Four mountain bike race for individuals and relay teams in Colorado, which includes racing on four distinct mountains in the Aspen-Snowmass ski area.
"9000 vert in just 36 miles!" Armstrong tweeted, a reference to the challenge posed by a course that features an 11 000-foot vertical gain and 9 000-foot vertical drop.
For good measure, Armstrong tweeted he is also planning to run in a marathon on Sunday.
His spokesperson Mark Higgins said neither event comes under USADA's jurisdiction.
