Driven by curiosity, wanderlust, and health crises, David Downie and his wife set out from Paris to walk across France to the Pyrenees. Starting on the Rue Saint-Jacques and trekking 750 miles south to Roncesvalles, Spain, their eccentric route takes seventy-two days on Roman roads and pilgrimage paths a 1,100-year-old network of trails leading to the sanctuary of Saint James the Greater. For Downie, the inward journey met the outer one: a combination of self-discovery and physical regeneration. More than 200,000 pilgrims take the highly commercialized Spanish route annually, but few cross France. Downie had a goal: to go from paris to the pyrenees on age-old trails, making the pilgrimage in his own maverick way.
