This summer, The North Face releases a series of videos looking into training for the prestigious Ultra-Trail du Mont-Blanc.
The UTMB starts and finishes in Chamonix, France, racking up 168 kilometers and more than 32,000 feet of elevation gain through the Alps along the way.
Last week the first two videos were released, including episodes shot with The North Face athletes Rory Bosio and Timothy Olson, the Western States 100-Mile Endurance Run record-holder.
