I believe that everyone that wins is doping considering the tremendous improvement in performance doping provides. We are not talking here about a minor boost, but a radical improvement.
How a clean guy can beat riders who can train much harder and longer, who can recover faster and who gain considerable more power and stamina thanks to doping?
I have watched sports for more than 30 years and the athletic improvement is mindblowing. And I believe most of it is due to better doping.
the use of artificial means [to improve performance] has long been considered
wholly incompatible with the spirit of sport and has therefore been condemned.
Nevertheless, we all know that this rule is continually being broken, and that
sportive competitions are often more a matter of doping than of training. It is
highly regrettable that those who are in charge of supervising sport seem to lack
the energy for the campaign against this evil, and that a lax, and fateful, attitude
is spreading.”
