And the people who keep accusing him are bitter foreigners who don't like it when an American wins in their "sport." You choose to accuse with no proof, and so in your mind all you can see is a guilty man because everyone else was doing it. Until you can prove that he actually used PEDs, quit with your accusations. Especially with my following point.
Armstrong has been competing in biking since his teens, as well as running marathons, triathlons and the like. He was a great athlete that finished in the 30s before being diagnosed with cancer. Something changed him when he had cancer - we don't know the effect that the radiation had on his body, or any of the other medicine was on. He literally had 1% chance of living and he beat those odds - at that point, you really need to think about the type of drive the man has, as well as his pain threshold and tolerance. The man would go freaking RIDE HIS BIKE AFTER CHEMO TREATMENTS. He basically expected to die so he chose the live those months of treatment as he enjoyed it, which was riding.
