Yes. Given the often stated fact about the number of samples which tested positive when retested later I think it’s quite clear that very few members of the peleton were doping (at least at some points in LA’s career).
But isn’t the ashenden work looking at those who were using synthetic EPO during the tour as opposed to ‘preparation’ before it – the alleged positive B samples all suggest routine microdosing during the tour itself rather than use in training in conjunction with other products, Isn’t it a little bit more likely that Lance was simply cheating more blatantly than others perhaps due to pressure of coming back to the tour.
Not to defend armstrong, just to note that its far too easy to portray him as some doping monster ruining the race for everyone else when there were plenty of other dopers operating in the peloton during that period many of whom may have ‘prepared’ but ensured they were not ‘hot’ during the race itself.
