Since the start of the millennium, racers have come to the Canadian Rockies to cheat Death in one of the world’s toughest ultramarathons. The 118km course begins and ends on a 4200-foot plateau, passes over three mountain summits, and not only includes over 17,000 feet of elevation change but a major river crossing at the spectacular Hell’s Gate canyon at the confluence of the Smoky and Sulphur Rivers.
