This week Liz Bonnin enjoys one of Britain's National Trails as she walks part of the Thames Path through Oxfordshire - meeting some of the people and animals who call the banks of this great river home. Ben Fogle is in Whitby on the Yorkshire coast to follow one of the nation's favourite dishes - fish and chips- from sea to fork and we return to the Dales and the farm of shepherdess Amanda Owen as the family celebrate Dad Clive's birthday.
