The OP is cuck. Look into the known facts re guys like Rosa, Hermens, Aden before believing that all of the E. African greats over the years have been/are clean. Keep in mind Rosa ran from the Tour de France when testing for certain drugs was initiated. He started with the Kenyans immediately and within one year they went from a decent group of runners to having scores of individuals in every event. Hermens and others followed suit with the E. Africans to this day able to avoid out of season testing. As testing improved, the numbers of guys breaking 13, 26 etc. dropped. The marathoners still have the best routes when it comes to avoiding tests, for now.
Are all the E. Africans dirty? No. But MOST of them are, and it's been that way for almost three decades. NOP is squeaky clean compared to E. Africa and N. Africa. And the OP knows this.
