Columbia Montrail put its Spring 2017 collection to the test at one of the most physically and mentally challenging trail running races in the world: the Columbia-sponsored Ultra-Trail du Mont-Blanc (UTMB). Located on some of the highest peaks in the Alps, UTMB is a continuous 103-mile race, which means no sleeping, just running for over 20 hours. To share the inspiring moments and trials of the race, we developed a special video, entitled Endure, currently featured on Columbia’s social media channels. See the trailer here.Endure features three of the participants from last year’s race: Amy Sproston, a Columbia Montrail-sponsored runner from the United States, and Columbia employees Ruy Ueda and Tomo Araki from Japan.
