You mean in reference to the Armstrong case?
Charly Mottet was the last clean general classification contender.
, Miguel Indurain was clean until 1993, but the performance jump between 1992 and 1993 just isn't human. Either he was already doping and stepped it up, or that's when he started doping. And I love San Miguel enough to give him his own Friendica page @Miguel Indurain (fan)
Between then and the bio-passport, everybody who won anything major blood doped.
Pretty much anybody who follows cycling (on the grounds that most cycling fans are cyclists first, and fans of the professional sport second) has known since 1999 Armstrong doped, but that's not the important part of this. The important part is the corruption heading all the way up to the top of the UCI. He should have had his title's stripped, but as with Riis, those years should list no winner.
Nobody else had early warning of drug tests. They weren't allowed to go for a shower before giving samples. They didn't make "donations" to the UCI following news breaking of positive drugs tests. Twice. They didn't have Pat McQuaid lying for them in public statements. The worst bit is, we don't even know which the lies are - we just know Pat McQuaid isn't consistent with his own statements.
It's unfortunate that things ended like they did - we've got nothing to celebrate until the UCI is either disbanded or entirely replaced...but on the other hand, Armstrong deserves everything he gets. Look at what he did to Lemonde (made the abuse he suffered as a child public, and got his sponsorship deals cancelled), Simeoni (spat on - literally - for talking about drugs), Bassons (harassed out of the sport for being clean), and so on.
