Lance Armstrong... greatest doper there was or ever will be

Regarding the peloton being slower... Testing is better meaning levels are stricter. For example you can't get a massive hit off EPO and expect to get away with.

A cynic would say this means riders are doping less, and not that less riders are doping.

That is the cynics take on it: the peloton is slower because the ones that are doping are doping smart, just enough to get them competitive and recovering quickly but not enough to set alarm bells ringing. The hole in that is the speeds they are going are physiologically probable, so achievable through conditioning, nutrition and training. I read something very important at that Sports Scientist blog: performance is not proof. Their analysis and that of other sports scientists (posting on the clinic) is that Sky's TdF performance doesn't set alarm bells ringing.

So your choice remains were they doping to a minimum, or were they well conditioned and executed their tactics perfectly? Of that TdF unit Rogers as a Ferrari client puts a big question mark. Froome also has gone from being average to GT contender. Wiggins for me has the pedigree and JV said he is certain Wiggins was racing clean at Garmin in 2009 and believes he is putting out the same numbers these days.

Cav is clean though
