Pilgrimage: The Road to Istanbul Episode Rating Graph

Seven well-known personalities, all with differing faiths and beliefs, put on backpacks and walking boots and, on foot and by road, set out to cover sections of the Sultans Trail - a modern-day, 2,200km pilgrimage across Eastern Europe, which starts in Vienna and ends in the historic city of Istanbul. Journalist Adrian Chiles, former politician Edwina Currie, Olympian Fatima Whitbread, comedian Dom Joly, actor Pauline McLynn, broadcaster Mim Shaikh and television presenter Amar Latif live as modern-day pilgrims, staying in basic hotels and often sleeping in shared rooms.
