JCA- Asked me to comment about the Lance Armstrong fall from grace.
In his situation is seems to me it was all about the money for everyone involved. His teammates were making money too so that is why it was kept quiet about Lance and the others doping issues.
I am a Spinning Instructor with over 20,000 miles logged on a Spinning bike so I understand the feeling you get when you think you could ride for hours without feeling tired. But to transfer that to making money , big money, by adding doping to the equation was a calculated missstep by Armstrong and his teammates. Just my opinion.
