Jennifer Pharr Davis knows a thing or two about endurance. Jennifer is a wife, mom of two, author, entrepreneur, and a record-setting long-distance hiker. In 2011, Jennifer set the record for the fastest completed hike on the Appalachian Trail, finishing the 2181-mile trail in 57 days, hiking nearly 50 miles a day. Jennifer stopped by to tell us about her new book The Pursuit of Endurance, the many parallels between entrepreneurship and life on the trails, the huge difference between stopping and quitting.
