That's what the cyclists like to whine about. But Patric Clerc, the Chairman of ASO talks about that in l'Equipe this morning (sorry, it's in French but I haven't seen these comments translated into English anywhere yet). He points out that the tour is less demanding than it used to be decades ago (3 rest days rather than 2, fewer mountain stages etc.) when doping wasn't an option. And he points out that the sport which everyone concedes is beset with by far the most intractable problem with doping, is track and the event competing in that sport which has the athletes who are the most recalcitrant about cleaning up their act & giving up the juice are in the 100 meter!. I think he has a point. It's not about the difficulty, it's about the fame & money. Or infamy & money, is probably more like it.
good points , thanks
