Clare Balding is in Durham for today's edition of Radio4's walking series, when she joins Maggie and Keith Bell. They take her on one of their favourite routes from their home, Crook Hall, through the outskirts of the city and along the river. The couple now use walking as a time to catch up, hold business meetings and relive memories of their courtship, when they both arrived in the city over thirty years ago as students.
