Matt Baker and Julia Bradbury are in the Cairngorms, a part of Scotland which has seen its heaviest snowfall in more than a decade. Matt makes the most of the icy conditions by taking part in the annual sled dog rally and finding out what makes a good racing husky. Julia helps to create a snow hole, which can offer a lifeline for people caught out in the mountains. Back on his farm in the Cotswolds, Adam Henson ensures his sheep and cattle get what they need to stay healthy through the winter, and John Craven heads to Herefordshire to investigate one of the biggest issues in rural Britain - its ageing population.
