Loose Ends embraces the great outdoors this week at the Kendal Mountain Festival. Stuart talks to festival patron and bestselling writer Robert Macfarlane about his "mountain DNA" and unusual walking snack. Broadcaster and writer Louise Minchin loves a mountain too. Having put aside the extreme working practice of rising at 3am for Breakfast TV she now loves a triathlon, a free-dive at night under ice or the extreme experience that is learning to cook a soufflé from an online video for Celebrity Masterchef. Space scientist Dr Maggie Aderin-Pocock - who is such a star there is even a Barbie doll in her image - on being inspired by the night sky, be that incredible telescope images or The Clangers as she was as a child. And for a counterpoint approach we have a relative newcomer to the country, the comedian Chris Cantrill who describes himself as a "rural imposter" and hosts a podcast about adapting to the northern wilds by competitive leek growing and donning a cape.
