His seven Tour de France titles stripped away and his legacy in tatters, Lance Armstrong is heading back outdoors and into the public eye.
A day after the U.S. Anti-Doping Agency punished Armstrong with a lifetime ban from professional cycling and erased 14 years of his career after concluding he used performance-enhancing druugs, Armstrong is scheduled to ride in a mountain bike race in Aspen, Colo., on Saturday and follow it up by running a marathon there Sunday.
And he has no plans to slow down any time soon, despite the whirlwind of controversy swirling around him.
Armstrong spokesman Mark Higgins said Armstrong also still plans to attend the World Cancer Congress in Montreal where's he scheduled to deliver a keynote address to thousands in attendance.
"He's getting out there," Higgins said.
Anti-doping and cycling officials will continue to address his career.
USADA said Friday it expects cycling's governing body to take similar action, but the International Cycling Union was measured in its response, saying it first wanted a full explanation of why Armstrong should relinquish Tour titles he won from 1999 through 2005.
The Amaury Sport Organization, which runs the world's most prestigious cycling race, said it would not comment until hearing from the UCI and USADA. The U.S. agency contends the cycling body is bound by the World Anti-Doping Code to strip Armstrong of one of the most incredible achievements in sports.
Armstrong, who retired a year ago and turns 41 next month, said Thursday he would no longer challenge USADA and declined to exercise his last option by entering arbitration. He denied again that he ever took banned substances in his career, calling USADA's investigation a "witch hunt" without any physical evidence.
USADA chief executive Travis Tygart described the investigation as a battle against a "win-at-all-cost culture," adding that the UCI was "bound to recognize our decision and impose it."
"They have no choice but to strip the titles under the code," he said.
That would leave Greg LeMond as the only American to win the Tour de France, having done so in 1986, 1989 and 1990.
LeMond did not immediately respond to messages requesting comment left through his attorneys and friends.
Armstrong on Friday sent a tweet about his plans to race in Aspen, but did not comment directly on the sanctions.
The UCI and USADA have engaged in a turf war over who should prosecute allegations against Armstrong. The UCI even backed Armstrong's failed legal challenge to USADA's authority, and it cited the same World Anti-Doping Code in saying that it wanted to hear more from the U.S. agency.
"As USADA has claimed jurisdiction in the case, the UCI expects that it will issue a reasoned decision" explaining the action taken, the Switzerland-based organization said in a statement. It said legal procedures obliged USADA to fulfill this demand in cases "where no hearing occurs."
If Tour de France officials follow USADA's lead and announce that Armstrong has been stripped of his titles, Jan Ullrich could be promoted to champion in three of those years. Ullrich was stripped of his third-place finish in the 2005 Tour and retired from racing two years later after being implicated in another doping scandal.
