This gripping documentary takes an intimate look at the grueling world of Kenyan long-distance runners, where athletes train in isolation to achieve their Olympic dreams through sheer sacrifice and dedication. We follow top athlete Geoffrey Kipsang as he prepares for a monumental challenge, pacing himself for a historic performance alongside the legendary Haile Gebrselassie in the 2012 Berlin Marathon, and watch as his fellow competitors, including Geoffrey Kamworor and Stephen Kiprotich, drive themselves to reach their full potential.
