On an antique map in Oxford's Bodleian Library, a faint red line threading through towns and villages between Southampton and Canterbury suggests a significant, though long-forgotten, road. Renamed the Old Way, medieval pilgrims are thought to have travelled this route to reach the celebrated shrine of Thomas Becket.

Over four seasons, travel writer Gail Simmons walks the Old Way, winding 240 miles between the chalk hills and shifting seascapes of the south coast, to rediscover what a long journey on foot offers us today. What it means to embrace 'slow travel' in the age of the car? Why does being a woman walking alone still feel like a radical act? Can we now reclaim pilgrimage as a secular act?

Blending history, anthropology, etymology and geology, Gail's walk reveals the rich natural and cultural heritage found on our own doorstep.
