This question has been on my mind for a long time, and I was reminded of it because of the comments on yesterday's T-A stage of 208km with that monstrous triple climb. Purportedly, those long and hard stages lead to (more) doping. Personally, I don't buy that, as the consequence would be that there'd be no doping if you were to turn every stage into, say, a 60km crit. Furthermore, the shorter the stage, the more riders do think they have a chance of winning, hence the higher the pressure on them, and the more incentive to dope. But maybe I'm wrong. What are the thoughts here in the Clinic?
