Countryfile

Charlotte Smith and Joe Crowley mark the 50th anniversary of the Viking Way, exploring the people, wildlife and history connected by Lincolnshire's famous long-distance footpath. They uncover evidence of Viking settlers, meet the volunteers who maintain the route, visit the Ramblers' Church and investigate efforts to protect water voles. Adam Henson explores high-tech strawberry farming, and John Craven launches Countryfile's annual photographic competition.
