Lance Armstrong Crashes in Race After Addressing Doping Allegations

Lance Armstrong began his Thursday by addressing his ex-teammate's doping allegations against him, and later tweeted about his own condition after taking a "face first" spill during a cycling race.

The seven-time Tour de France winner spoke out Thursday morning about allegations hurled at him by cyclist Floyd Landis, who once biked on Armstrong’s team and, according to the Associated Press, alleged in e-mails that Armstrong used to dope with him and taught other cyclists how to do so as well.

"Obviously everyone has questions about Floyd Landis and his allegations," Armstrong said. "I would say that I'm a little surprised, but I am not. In all honesty, this has been going on for a long time. The harassment and threats from Floyd started a few years ago and really, at that time, we largely ignored him… A year ago, I told him, 'Listen, you do what you have to do.' We have nothing to say and nothing to hide."
