The Whithorn Way follows an ancient pilgrim route from Glasgow to Whithorn in Dumfries and Galloway. In this episode, Mark and Rachel focus on the start of the journey at Glasgow Cathedral. Mark and Helen cycle down to Glasgow Green and imagine how pilgrims would have crossed the River Clyde. They then follow the River westwards to the new Govan- Partick pedestrian bridge. In Govan, they meet up with Rachel and go to the Govan Old Kirk where there are some unique Viking graves.
