As cycling booms, Matt Baker and Ellie Harrison jump on their bikes to explore a new greenway in Warwickshire. It’s the latest National Cycle Route to open in the UK. Matt hops off to discover the secrets of Britain’s mini-dinosaur, the great crested newt, and meets the people moving heaven and earth to protect them. Ellie goes in search of the water vole, one of the UK’s rarest water mammals, and meets a walking group who are mapping and reviewing thousands of accessible walkways in a whole new way. Adrian Chiles has a go at a local tradition in the village of Upperthong in Yorkshire, while Adam is in for a surprise when he welcomes Lexi the Suffolk Punch’s new foal. And Tom Heap investigates the increase in cycling deaths on our rural roads.
