The topography explains it all. https://geology.com/articles/east-africa-rift.shtml
tl;dr The people of that area in East Africa naturally live close to sea level, however there are easily accessible elevations changes that distance runners have trained on for probably centuries. It turns out that training at high altitudes and recovering at low altitudes provides a tangible and demonstrable advantage compared to just single elevation training.
This can't be the whole story, otherwise we'd see places like Chile, Peru, and India competing too
India? the sea and the himalayas are too far apart to compare.
India's Deccan Plateau is about as elevated as most of Kenya's highlands and takes up basically the entire land area of India that sticks out into the ocean
The air sucks in India too
Yeah like the other commenter said this isn’t it, nobody is commuting up and down 10,000’ on a regular basis, especially in antiquity. Just because different elevations “look close” on a map means nothing.
Far more likely is this is a concentrated population of folks with highly desirable traits for distance running.
The school of thought has generally changed.
Live high, train low is now the prevailing methodology.
That’s good. I thought the map was being racist
The map is being racist by labelling Canada, Morocco and USA but not the super-relevant African countries. I'm baffled by that...
Like, I don't think it's intentional but how does that happen?
Maps aren't racist. Map owners are racist. Map creators are just filling demand.
(replace "maps" with "dogs" and "racist" with "at fault for dog eugenics")
Those Ethiopian and Kenyan runners live and train at high altitude, when they compete at lower elevations where there's more oxygen, they have a dramatic edge over other runners.
I'd wager we would see the same effect if athletes from Bhutan, Nepal and/or Tibet decided to compete in long-distance running.
Genetically I imagine the Africans have a more advantageous stride than the Asians?
Not to say the biomechanics are equal, but Cheptegei the current 10K record holder is 5’6” / 1.67m. So it’s not like an Usain Bolt situation. And for the marathon, Mo Farah is 5’9”.
I remember hearing during the Olympics them actually talk about how much of a freak Bolt is to be so tall and so fast. Most runners are on the shorter side. For those that watch the NFL you'll know that being tall and fast is what makes people DK Metcalf such a freak of nature when sprinters are actually usually smaller, like Tyreek Hill. It's less about stride length and more about power put into the ground which is easier for shorter legs.
If you watch Bolt run you'll notice he doesn't actually hit his peak until way after the other runners during the 100m. He has said before iirc that he's actually a more natural 200m runner rather than a 100m runner. On the 100 he barely gets to his top speed before the finish. That's what makes his 100m records truly so phenomenal, he's not really built for that race but was still so much faster than everyone else on the track.
It's not out of the realm of possibility that a runner from Nepal being Asian and therefore statistically likely to be shorter than someone born in Africa, could be a record breaking runner. Of course this is all about sprinting but over longer distances the longer lankier bodies prevail, better momentum.
tldr: short legs go zoom, long legs go long.
Africa is more diverse than the rest of the world put together.
Which particular Africans are you referring to?
As OP and not the poster you are asking, I'll answer this one:
Ethiopians and particularly Sudanese (then zooming in even more specifically - the Nuba tribe) are known for being among the tallest people in the continent today.
It was right around this area where the Kush people of the Nile Valley Civilization flourished in antiquity. The Kush are described by accounts of the era as being taller than any other Mediterranean groups.
Relative genetic isolation since then results in that they were tall then, and they are tall now. Some of this genetic heritage must have also spread down to Kenya in the interim.
This is why the US Olympic Training Center is in Colorado.
Thanks for adding context.
Also a region with good coffee. There must be a correlation…
I wonder how much caffeine doping goes on before races. It sure as hell gives me tons of energy
More likely the altitude helps with training & coffee growing, but a little caffeine never hurt
Explains the shit streaks
Crazy that most of them come from the same place as our earliest ancestors from 200.000 years ago. Must be a magical place.
Hasn't there been an older skeleton found in Morocco now?
Would explain the three dots there.
No it wouldn't
Yea but imagine if it did
Whoa crazy
They'll run as fast as Kenyans!
400 BABIES!
ENERGY LEGS!!!!!!!
the ones in America are ethnically the same ones in Africa
Who are you talking about? Galen Rupp? Grant Fisher? Chris Solinsky?

somebody forgot to label something
east africa isn't real, it can't hurt me
Persistence predator go brr. Epidemiology implies genetics are likely involved.
