In this first episode, the intrepid eight arrive in Martigny, Switzerland, and find out for the first time who will be sharing their pilgrim adventure. They make their way by mountain train to the start of their pilgrimage in Orsieres, high up in the Swiss Alps. The Via is based on a journey taken to Rome in 990AD by Archbishop Sigeric of Canterbury, which crosses the Alps at 2,500m and goes over the Great St Bernard Pass. Like Napoleon, his 40,000 strong army and the pilgrims before them, the group also have to make their way up the challenging mountain path.
