I love this documentary that is narrated by Eamonn Coghlan. It is a glimps into what the Kenyan way of life is, and their approach to running. The main man behind such of the success is an Irish man by the name of Br Colm O' Connell. His holistic approach to coaching is why I believe he is so successful.
Take an hour out of your day to get you motivated for the long run at the weekend.
