Two-time U.S. Mountain Running Champion Morgan Arritola has a no-nonsense approach to running up tall mountains. She'll compete as part of Team USA in the World Mountain Running Association World Championships on Saturday, Aug. 16, 2014. The race will run in conjunction with the Pikes Peak Ascent. Tho)ugh she has never run in the Ascent, she's not worried. "It's better to run a little dumb, I've found," she said.
