Renowned as a mecca for trail runners, the Chamonix Valley and Mont Blanc region is home to some of the greatest trail running races in the world, including the Tour des Géants and Ultra Trail du Mont Blanc. The landscape, with its dramatic mountain scenery and ethereal vistas, offers diverse trail options and true adventure - the perfect playground for this exhilarating sport. 

Kingsley's love of the mountains started as a 5 year old. It wasn't a big surprise that he studied geography and glaciology at university. He's climbed the north faces of the Eiger, Matterhorn and Grandes Jorasses in the Alps, and led expeditions to mountains all over the world. Through mountaineering he developed a passion for a minimalist approach in the mountains, and soon discovered trail running as an ultimate form of fast and light travel. He runs a mountain running and guiding company (www.icicle.co.uk), and so divides his time between the Alps and the Lake District each year.
