I've read through Renato's posts for, I guess now, years. When he began to talk about each of his athletes' blood and how he has tested their blood,I was suspicious. He's taking blood? At regular intervals? Come on...
This is not surprising to me. Time will tell. I would imagine if there are strict doping controls in London, the Kenyans will not compete well. At least, whoever they send will not compete well.
Your post started off bad and then went downhill. I don't necessarily trust Canova, or the managers he is associated with, but understanding blood is not indicative of doping.
Also, Kenyans have fared extremely well at all the major marathons and the last few Olympics/World Championships - which have all had testing. Again, that doesn't mean they actually are all clean... but if they are dirty... they will not be caught at the Olympics.
