4 Extra Debut. Robert McFarlane walks some of our ancient pathways, starting on the chalk of The Icknield Way. Read by Dan Stevens. From July 2012.

"Humans are like animals and like all animals we leave tracks as we walk. Pilgrim paths, green roads, drove roads, corpse roads, trods, leys, dykes, drongs, sarns, snickets, holloways, bostles, shutes, driftways, lichways, ridings, halterpaths, cartways, carneys, causeways, herepaths."

Author Robert Macfarlane follows some ancient routes in the UK and overseas. As well as having adventures on the way - as you do on foot - he ponders the creation of old paths, the people who trod them, and how they resonate in today's landscapes.

Setting off, Robert Macfarlane hits England's chalk paths and soon finds out there's a price to pay for this..
