It's fast, it's furious and it's brutal - the Carnethy 5 started over 40 years ago and is the first hill race of the season, when the weather can vary from brilliant sunshine to deep snow. This year 600 hardy competitors battle it out over the Pentland hills just south of Edinburgh.
Also in this month's Adventure Show we're going behind the scenes with the Tweed Valley Mountain Rescue team. We head into the wintry hills with Cameron McNeish and we've got an inspiring story about how a special bike is transforming the life of someone who suffered a major stroke at a young age.
