Former Irish athlete and 5,000m world champion Eamonn Coghlan travels to Kenya's highlands to uncover a little-known story - the role of Irish missionaries in securing Kenya's dominance in world athletics. He meets Brother Colm O'Connell, a modest priest who played a major role in fostering Kenyan distance running and who is now considered one of the world's top athletics coaches. Watching him train the 800m world-record holder David Rudisha, Eamonn observes at first-hand his unlikely but lasting legacy. Part travelogue, part tribute, the documentary also features an interview with Eamonn's childhood hero, the great Olympic athlete Kip Keino.
