According to Competitor Group, Kenyans are good runners, especially in marathons. Studies reveal that the athletic abilities of Kenyans are innate. Kenyan athletes are tall and have less body mass, short torsos and long legs. These traits make them highly competitive in long races.
Kenya has dominated in most competitive races, such as the Boston Marathon. Most of the athletic champions from Kenya come from the western part of the country. Reader's Digest reveals that top runners from Kenya were born in the county's highlands, which have thin air. Training in high altitude regions allows Kenyan athletes to develop powerful lungs and hearts. This makes them highly competitive at sea level.
