It's funny how you don't seem upset at all that Kenio has tarnished his own reputation, and that of Kenya's (in this year of disgrace) by funnelling millions of dollars away from young athletes seeking their own Olympic glory just so he can buy a bigger house and more expensive clothes.
1. Kenya's success was almost overnight in the 60's. Previously, they had been useful pacemakers in the UK in the 50's, with no apparent ability to last the pace. At one such meet, a Dutch doctor was famously in the stand, took one look at the long limbed 2% body fat African runners leading, and promptly told journalists that Kenyans were genetically superior runners. Within a few years, he was head of Kenyan athletics and his athletes were beginning to dominate. The only hiccup was in the summer of 1968, when Kenio and the rest were underperforming after a 'revolt' (led by Keino) had deposed him from his position, to which he was restored just in time for Mexico.
2. Yeah, no excuses, Ryun could have gone to train in Scotland.
3. Yeah, thanks for pointing out that Kenio was in a hospital bed as far as the other runners were concerned and were surprised to see him lineup (Ryun didn't follow his pace because he feared Keino would literally die having been told he was near death in hospital), yet the other Kenyan still rabbitted him as per team instructions. Very odd.
