No. There is a hugely disproportionate number of Americans and British of Somali, Kenyan, and Ethiopian origin who excel in world class distance running (Adbirahman, Farah, and many more, including a big new wave of Somali American after).

Interesting. That still wouldn't completely rule out environmental/cultural factors though, including diet and so on (e.g. maybe eating teff is good for long-distance runners).
But don't most Kenyan and Ethiopian marathon winners also grow up in Kenya or Ethiopia? I.e. how do we discount at very least environmental factors (including, for instance, diet), even if you doubt cultural ones?
