Lance Armstrong has been dogged by accusations that he used/uses banned substances. Some people think it's impossible for him to have dominated the Tour de France without cheating. But if these accusers would stop to think, they'd realize how silly they are. Armstrong has been dominating events since he was a schoolboy. I've heard stories from eyewitnesses about how he lapped the entire field in a Fort Worth criterium. At the tender age of 21, he beat the world's best cyclists (including three-time Tour winner Miguel Indurain) in the World Championship road race in Oslo. Here is video. Was he using banned substances in grade school, when he was beating grown men in triathlons? Was he using banned substances already in 1993, at the age of 21? The man is a physical freak. He is also fanatically disciplined when it comes to training. He doesn't need to cheat, so why would he?
