Clare Balding walks the length of St Oswald's Way in Northumberland. Clare walks the third stretch of the route, from Alnmouth to Warkworth, in the company of local artisit Sue Fenlon and photographer Barbara Aitchison. They explain why they find this part of the Northumberland coast so inspiring. St Oswald's Way is a 97-mile route, running from Holy Island in the north, along the stunning Northumberland coast before heading inland to Heavensfield and Hadrian's Wall. The path links some of the places associated with St Oswald, the King of Northumbria in the early-seventh century, who played a major part in bringing Christianity to his people.
