The main reason for Kenyan success is not doping, anyone who follows athletics just a little bit knows this.
Your only alternative ('natural born running genes') is just one of many reasons for their success. Those reasons are well known since decades: hard training, running since childhood, nutrition, easy lifestyle, altitude, tradition, financial incentives and so on.
I disagree.
East African countries went from being strong distance running nations to completely dominant pretty much at the time EPO became available. Particularly as they had full support of Lamine Diack, who saw the sport as not being fair on Africans and had a strong interest in 'levelling the playing field'.
Nobody is saying they wouldn't be successful if doping was never a thing, they probably still would have been the strongest nations. Just not at the ridiculous level of dominance that they have enjoyed for the last 20-25 years.
