The secret is that there is no secret, just a myriad of helpful cultural and environmental factors of which not a single one is the driving force.

Mr. Kipchoge is definitely a product of his surroundings and culture, as we all are. However, now it is clear what drove him to make these claims and put everything on the line to make it so. Most of all it was a great travel story and it enthusiasts me to head down south there once myself.
