Launched in 2017, the Under Armour Mountain Running Series is a trio of trail races that take place in Copper Mountain, CO, Killington, VT and Mt. Bachelor, OR. The first 2018 race concluded last week in Copper Mountain, CO where the base elevation was 9,800 feet and the peak elevation during the longest race, a 50K, was 12,000 feet. Runners completed either a 5K, 10K, 25K or 50K mountain run full of steep climbs, rocky terrain and beautiful woodsy downhill single track trails.
