Last October, Honnold set out to climb the entire skyline of his backyard stomping grounds, the Red Rock range in Las Vegas, NV, calling the challenge "Honnold's Ultimate Red Rock Traverse" (The HURT). In 32 hours of nonstop running, scrambling, and soloing, he covered 35 miles of rugged desert terrain, with over 150 pitches of free solo climbing - both up and down - and logged 25,000 vertical feet of elevation gain.
