After years of watching Kenyan athletes win the world's biggest races, Adharanand Finn set out to discover just what it was that made them so fast - and to see if he could keep up. Packing up his life he moved from Devon to Iten, in Kenya, to eat with, interview, sleep beside and - most importantly – run with, some of the greatest runners in the world. In the distance rests his dream, to join the best of the Kenyan athletes in an epic first marathon across the Kenyan plains.
