Something to think about, when racing did you ever come across anyone who seemed superhuman, unbeatable, miles ahead of the rest, but did not do any more training that the rest, and could not have possibly have been taking drugs! I have when racing as a junior, someone who used to train with us from a rival club, at that age in Ireland I doubt they were taking drugs to further their athletic ability. Yet he was able to beat his seniors and even beat a few that were pros in Europe. No drugs. That far ahead of everyone else!
Can the same be said for some pro's are some of them extraordinary talented / freaks of nature who can carry out superhuman type sporting feats?
