Countryfile: Peak District

The team is in the Peak District, where John Craven looks at the secrets this familiar landscape is hiding deep underground. There's the precious shining mineral called Blue John, of which a new seam has just been discovered, thanks to a family riddle. In 2014, part of the Tour de France cycle race route will take in the highs of the Peak District. Ellie Harrison tests out part of this challenging route with a seasoned cyclist. Along the way she finds out the history of a very special site where tanks were tested ahead of going to the front in World War II. Helen Skelton is also in the Peaks, in the village of Tideswell which is trying to persuade local people to buy their food from the village shops. She takes part in a local initiative which teaches people where their food comes from in the countryside, and also learns to shoot at targets and then cook up a delicious game pie.
