I'm not the expert that many here are on track and athletes, and I don't post much. I also don't buy into the endless claims I see here of doping. But there is no way you can't be suspicious of this Koech guy. The minimal record on Koech on World Athletics and the staggering improvement. The online pics in a Google search do not show a guy who looks 18. The ease of his wins over world class fields in 3:27 and 3:28. He looked like he could run sub-3:26 today. Would it surprise anyone if he did at his next meet? It all looks incredibly suspicious to my untrained eye.
