10. The Kalenjin Of Kenya Are The World’s Best Long-Distance Runners
Everyone knows that Kenya has the world’s best marathon runners. What most people do not know is that the majority of these runners are from the same tribe. Enter the Kalenjin, the world’s best long-distance runners.
Several scientists, researchers, and sports analysts have tried to explain why the tribe dominates long-distance running. Although their starch-rich diet, the location of their homeland, and coincidental social and economic factors have been fingered as possible reasons, no one has come to a definite conclusion. However, it is suspected to have something to do with genetics.
The Kalenjin have small ankles and calves and a slim stature, which is just perfect for marathon running. Body size is important in determining who will win a marathon because people with smaller ankles and calves use less energy than others. It is even said that one can guess the winner of a marathon by checking which of the contestants has the smallest ankles and calves.
