American ultrarunner completes barefoot trek of California’s John Muir Trail

August 29, 2022

New York-based ultrarunner Kenneth Posner completed a 22-day trek along California’s 210-mile (337K) John Muir Trail on Saturday. While Posner didn’t run the route, he is an avid trail runner and ultrarunner, and he almost exclusively runs barefoot. He didn’t take to the JMT to break any official records, but rather for a personal challenge: to hike the entire trail without shoes. CRM
