“Cool, Autumn Loop Through the Pines, Golden Aspen and Red Maples” sounds like the tag line for a fun local 5K. In Logan, it’s how the Bear 100 advertises itself, a 100-mile trail ultramarathon with over 22,000 feet of vertical climb (carrying survival equipment is recommended). Runners contemplating the Bear 100 would do well to consider the Olympus, a trail shoe with extra cushion for going the ultramarathon distance.
