Kenya: The secret why Kalenjin Tribe is reigning over long distance running

David Epstein, a former senior writer at Sports Illustrated and author of the new book The Sports Gene stated that the statistics when it comes to this sports event are “sort of laughable”. “There are 17 American men in history who have run under 2:10 in the marathon. There were 32 Kalenjin who did it in October of 2011,” he said.
