In the last of three programmes exploring our experiences of travel and why we do it, Lynne Truss joins Will Parsons, co-founder of the British Pilgrimage Trust on a short pilgrimage along the Old Way in East Sussex. They begin under the ancient Yew tree in Mary and St Peter’s Church in Wilmington and walk via the Long Man and Saint Peter of Vincula in Folkington to St Andrews’ Church in Jevington. The journey offers Lynne a chance to discover what a pilgrimage is and how it differs from a walk. Aided by her pilgrim’s staff it proves to be a journey of unexpected encounters and experiences for Lynne - unnerving, calming, reflective and enjoyable. Producer Sarah Blunt
