3. Lance Armstrong (2005)
Part of the reason the French press had it out for Lance Armstrong when he was winning those 7 consecutive Tour de France titles was that everyone knew there were drugs available that current tests couldn’t detect. (The other reason they had it out for him was that they didn’t like an American dominating the Tour. That was their thing.)
But the anti-doping agencies were smart. Since they knew riders were certainly using drugs they couldn’t yet detect, they would freeze samples to test at a later time. And in 2005, according to French sports daily L’Équipe six of Lance’s samples from 1999 tested positive for EPO. Later it was revealed that the samples weren’t handled properly, and the AFLD (the French Anti-Doping Agency) asked if Lance would like to re-test other frozen samples to confirm his innocence. But Lance declined, saying the results wouldn’t be valid since they couldn’t confirm the samples had been stored properly.
But here’s the deal, everybody: Lance probably did use PEDs. That doesn’t mean he wasn’t a great cyclist. They all use them, so it’s not like he had a leg up on competition.
Would it be nice if Lance were some god-like specimen able to beat mere mortals, au natural, even though they are using high-tech blood transfusions to boost their endurance? Sure. But he’s not, and he didn’t. Accept it.
