Ever since he won his first Tour de France, people have been whispering about Lance Armstrong's possible blood doping.
That's where athletes remove some of their red blood cells, put them on ice, wait until new ones grow then inject the extra blood cells back into themselves right before a race.
What that does is allow them to move more oxygen more efficiently so they can go harder for longer.
Lance said he's given over 500 samples to prove he's never blood doped, saying:
"I'm not wasting any more of my time talking about it and you shouldn't waste your time talking about it. Let's move on."
We just think everyone is jealous they couldn't win 7 Tour de Frances in a row.
We believe you, Lance.
That means drop it, everyone else!
