The disgraced cyclist Lance Armstrong has said that he has been through a "difficult couple of weeks", as he faced a catalogue of doping allegations.
He was speaking at an event to mark the 15th anniversary of his cancer charity, Livestrong, in Texas. Earlier this week he stood down from his role as chairman.
The charity event was attended by about 1,500 supporters, including some of Hollywood's biggest names.
