Kingsley Jones has climbed the north faces of the Eiger, Matterhorn and Grandes Jorasses in the Alps, and led expeditions to mountains all over the world. His passion for minimalist mountain travel led him to discover trail running as an ultimate form of fast and light travel. He runs a mountain running and guiding company (www.icicle.co.uk), dividing his time between the Alps and the Lake District.
