ForĀ the second episode of Mountain Air, a podcast series recorded in association with UKHillwalking, Dan Aspel meets Zac Poulton, one of the Lake District's three Fell Top Assessors, whose daily reportsĀ from Helvellyn provide an invaluable winter resource for hillwalkers and climbers. But that's only part of the story. From guiding in the Himalaya to hallucinating on Wainwright's Coast to Coast route, his outdoor career has been rich and varied. "Keep saying yes, keep doing a good job, and the doors will keep opening" he says.
