why are kenyans so good at running

Kenyans are so good at running primarily due to a combination of factors rather than a single cause. Key reasons include genetic predisposition with favorable body types such as lean muscles and long legs (especially among the Kalenjin tribe), extensive early-life walking and running that builds high aerobic capacity, living and training at high altitude (Rift Valley) which enhances oxygen uptake, a traditional diet that supports endurance, and strong motivation driven by economic and social aspirations. These factors together create an optimal environment for developing world-class middle- and long- distance runners. Additionally, a rich local running culture and community support inspire young athletes to pursue running at an elite level, further fueling Kenya's dominance in the sport.
