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.

John Craven visits the Mardale Valley in Cumbria. The Lake District is one of the best-recognised landscapes in Britain, but in this neck of the woods, it's all set to change.

At Haweswater Reservoir, John meets the people behind the new radical thinking to boost biodiversity. John also enjoys a very special breakfast with one of our rarest mammals, the red squirrel, and he meets wildlife film-maker and photographer Hamza Yassin to launch this year's Countryfile photographic competition with two new categories for children and young people. Adrian Chiles lifts the lid on Manx customs on the Isle of Man, Adam sells one of his prized Gloucester bulls, and Charlotte Smith investigates the recent poisoning of sea eagles in Southern England.
