Amsterdam based production company A Cow Says Moo made a documentary about Kenyan athlete Geoffrey Kipsang; The Unknown Runner. It follows Kipsang training for his running debut at the Berlin Marathon. The documentary makers had unprecedented accesses to the training camp in Kenya and the marathon in Berlin. Interviews with Haile Gebrselassie, Stephen Kiprotich and Renato Canova complete the story. If these names get you excited this is a documentary for you. But if you simply like to get inspired by documentaries that show you ‘out of this world,’ you should too. The film is now available until 3rd March on Vimeo on demand. The trailer can be found here.
