The idea that we can generalize about people from any demographic is ridiculous. Poor people cheat. Rich people cheat. Why did all those super-rich parents pay bribes so their kids could go to USC or Yale? They did not need to do so. Their kids would have been fine. Regina Jacobs had degrees from Stanford and Berkeley and she doped! Lance Armstrong had more than enough money. So did Barry Bonds.
That said, if we do want to generalize. It seems obvious that someone who is a "herdsman" as a teenager might have been living a life more likely to lead to running success than that of a typical American. Rojo--do you think if you grew up in Kenya and worked as a herdsman (or worked on a farm in rural America) your whole life and then turned to running, you would have been better? Of course you would have. . . . It also seems obvious that someone who grew up in poverty would have more incentive to work hard and endure the pain of a sport like running.
In the past five years, this site has shifted in a really nasty way against Kenyan and Ethiopian runners. Before there was a sense that these runners represented the best of the sport: hard training at altitude on dirt roads. Now, unfortunately, it has indisputably become clear that some of these runners on these dirt roads are also cheating. In other words, it is now clear that Kenyans and Ethiopians cheat just like everyone else. But now a lot of people act like it is just absurd to think that any Kenyan and Ethiopian runner can do well without doping and that is the Americans who must be clean. It is like people think that running on concrete sidewalks in subdivisions followed by an afternoon of TikTok videos and burritos is better than running on dirt roads in the country followed by work in the fields and a whole-food vegan dinner. Rather than treat the Kenyans and Ethiopians like we would treat a runner from, say, the Netherlands or England or the US, people act like it is absurd that these Kenyans and Ethiopians could run. . . . It is like the morning of the 1960 Rome Marathon with all the Europeans feeling sorry for the poor bare-footed Abebe Bikila (if letsrun.com were around in 1960, the board would have been accusing Bikila of cheating).
