How many of us would love to spend a day walking with Chris Townsend? Someone well known around the world as an outdoor writer, photographer, blogger, conservationist, head of the Mountaineering Council of Scotland and long distance walker extraordinare. Well David Lintern was one such lucky guy and joined Chris for a long walk in January 2011 in the deep snow on the Cairngorms. This is the first of a fascinating three part series where they walk together and discuss the art of long distance walking.
