Ben Fogle goes on an East Anglian journey, starting high in the skies over Tibenham, and ending on race day at Newmarket. En route he walks the ancient Peddars Way, climbs high into the canopy of Thetford Forest, and learns how prehistoric hunters carved axes from the jet-black flint of Grimes Graves. Along the way, Ben looks back on the best of the BBC's rural programmes from this part of the world.
