After attempting to traverse the John Muir trail's entire 212-mile distance twice before without success, Josh Mathe decided to run it on his third attempt. His recent memoir In the Footsteps of Greatness, Mathe details his time on the trail, from Yosemite Valley to the peak of Mt. Whitney, and what he found both outside of and within himself.

Mathe's next goals include completing the Leadville 100 mile ultramarathon, biking across the U.S. with his father, and filming an international running documentary. Mathe will be doing a reading and signing for a brand new book at Time Tested Books on August 21.
