The Pilgrims' Way is about 190km (120 miles) long and runs from Winchester to Canterbury or London to Canterbury depending on which route you take and what you think of as being 'official'. The route from Winchester to Canterbury can, from Farnham, be walked along the North Downs Way. The Pilgrimage can about after the death of Thomas Becket (canonized in February 1173) and the site is now considered to be the most holy in Britain.
