I think some will say that the riders may come into the event with all the banned substances out of their system, but that they may benefit from banned substances during training, if done in low enough doses, and with fingers crossed they don't get randomly tested. This is the weak spot in the testing, no? Less concerned that someone gets tested after they win a stage at the TDF. It is the lead up, in the shadows, that a lot of people are worried about.

I'm generally of the thought that even if doping does still occur, the goal should be to keep the costs of [getting caught] cheating high compared to the benefits. If WADA (or whoever) can limit the benefit through better detection, random testing, etc., that is a good thing, as it moves in the right direction. And if people are forced to do microdosing to avoid detection, the hope is that the efficacy keeps dropping as the amount of that can be detected also keeps dropping. Maybe people have a 5 in 10 chance of getting caught, whereas before they had 1 in 10. Fewer people willing to risk it because the benefits to doping get smaller and smaller, less doping; that's a win.
