Martin Hügi is taking an unconventional approach to his long distance hike from Land's End to John O’Groats. He’s planned the route so he can visit as many ancient and veteran trees as possible. It’s a busman’s holiday as his day job is with the Woodland Trust and it's their Ancient Tree Inventory, created in collaboration with the Ancient Tree Forum and the Tree Register, that he’s using to guide him. He’s taken a four month sabbatical from work and Clare is joining him in the early stages of his trek near Marlborough in Wiltshire.Producer: Karen Gregor

Clare Balding and guests share inspiring conversations while walking in the great outdoors.Fresh air and nature, wonderful views and uplifting chat, each week Clare hikes in a different part of our glorious countryside. Walking side by side is the perfect way to cover a huge range of subjects: literature, art, wildlife, nature, taking on personal or physical challenges, dealing with grief, confronting preconceptions about the kind of people who love to ramble. The conversations are as varied as the landscapes we find ourselves in. If there's a recurring theme, it's the accepted truth that 'solvitur ambulando' - 'it is solved through walking': The sense of wellness, the benefits to mental health, easy companionship, or sometimes just the sense of solitude that being alone in nature brings.Few things are better than going for a good walk. That's what we aim to share each week on Ramblings with Clare Balding.
