Doping in sport is a fact.
And here comes Renato Canova and tries to show that it is possible to run fast without doping because he has witnessed that over and over. I believe all Renato wants is to inspire and to push runners to greater levels. He's been doing that for over 15 years, here on these boards. Not once he called dopers idiots, but that's not the point. It's a shame that many would read his posts and all they conclude is the doping.
Here, you can read Renato's posts to get to know him and his point better:

It's amazing how generous he has been, over and over answering questions, sharing training plans (as he always says, it's not the plan, it's the connection and relationship between an athlete and the coach), and being honest.
"Remember always the 3 most important points of a good training : CONTINUITY, GRADUALNESS and MODULATION."
And something he says about himself:
"I loved athletics from when I was 12 years old. At that time, I decided that, grown up, I wanted to become Italian National Coach.
But I never was interested in top results for myself. My motivations are basically two : to investigate what is possible to do with the human body, where for human body I want to mean physiology and psychology, finding the personal key for the best way of improvement (that is different one from another), and to help the athletes in improving their personality and their life.
I believe very much in the role of athletics (and of every type of sport, generally) like education for the life.
My principles are the principles of a teacher, before than a coach. I think that I'm at first an educator, secondly a coach.
This is the reason because I cannot accept in my mind not only any type of doping, but also any type of help from external sides. I think that the greater strength is in the mind, and I work for increasing the self confidence in my athletes."
