Armstrong Tells Of 'Difficult Few Weeks'
Lance Armstrong has said he has been through a "difficult couple of weeks" and urged supporters of his cancer-fighting charity to stand behind its mission.
The former champion cyclist made the remarks last night at the 15th anniversary celebration for Livestrong, the charity he founded in 1997.
He stepped down as chairman earlier this week in an effort to ward off damage caused by doping charges against him.
The event drew 1,700 supporters, cancer survivors and friends who gave him a standing ovation before he spoke.
Armstrong, who denies using performance enhancing drugs to win the Tour de France seven times, did not address doping evidence presented last week by the US Anti-Doping Agency (Usada).
Usada banned Armstrong for life because of his involvement in "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
Armstrong did not fight the charges, although he insists he never cheated.
The Usada report sent shockwaves through the sport of cycling.
On Wednesday, Armstrong was dumped by Nike, Anheuser-Busch and other sponsors.
