Don't know what to think about Lance. I raced bicycles off and on from 1973 though about 2003. Been reading about what a phenom Lance was since he was 16 years old. When the Nike commercial came on where Lance said "what am I on? I'm on my bike 8 hours a day!", I responded hell yeah.
I don't know what really happened. I do know that the sport of bike racing has always been on the leading edge of sports physiology, and also on the leading edge of Performance Enhancing Drugs and detection. In the 1950's, some racers took strychnine for performance enhancement for some reason (isn't that a pesticide?). I think it was the East Germans who invented blood doping, which is removing your own blood during a rested state and re-inserting it just before a race, providing more oxygen carrying capacity for higher endurance. No drugs, just your own blood. There was no way to test for your own blood being in your body, but you can detect the presence of trace elements of the plastic bags they store the blood in. EPO is a drug given to boost red blood count in anemic people. Again, higher red blood count equals higher oxygen carrying capacity for endurance races. Also can turn your blood to jello, causing stokes. Its pretty easily detected.
There are also the drugs you hear about in US mainstream sports (steriods, amphetimines, etc), along with masking agents (drugs that do not enhance performance but hide the presence of PEDs).
The protocols for detecting these doping controls have been in place for a long time.
Its hard to belive that one could get by doping controls so many times.
From what I have read about the USADA, they serve to clean up the sport by prosecution. No prosecution, no reason to continue to exist.
Floyd Landis, Tyler Hamilton, and Alberto Contador all served supporting roles for Lance Armstrong's wins, then all wanted to be Lance Armstrong. All won the TDF and were subsequently stripped of the title. Sounds like sour grapes.
George Hincapie, on the other hand, rode in support of Lance in all his wins, and while he could have become a champion in his own right, continued to serve a supporting role for others in their TDF wins. Met Hincapie briefly at a reception in 96 before the Atlanta Olympics; didn't say much. Still doesn't. If he ever does, listen.
