To celebrate Countryfile's 30th anniversary, John Craven takes us through 30 of the most memorable moments from the programme from the past three decades. Matt Baker meets local legend Joss Naylor, who has been running over Cumbria his whole life and is known as the king of the fells. There's a look back over some of the big news stories covered by the programme, including foot and mouth. Tom meets a farmer featured at the height of the outbreak to see how he's coped. There's also a look at some favourite wildlife encounters and Ellie meets the students who could become the future of wildlife film-making. We revisit some of the quirkier events in the rural calendar, such as the world nettle eating championships and the world tin bath racing event. Steve Brown is on Ullswater meeting those on a quest for the Holy Grail of the boating world. Countryfile has often travelled abroad to see what we can learn from our farming neighbours and Adam is in France hearing how ancient methods of farming could be the future.
