Speed Hiking the Appalachian Trail - Jennifer Pharr Davis

Jennifer Pharr Davis hiked the entire length of the 2,181 mile Appalachian Trail in 46 days, 11 hours and 20 minutes. The 2012 National Geographic Adventurer of the Year didn't run, she simply hiked very long days and slept short nights. But she tells Boyd that her next challenge won't be to break her own Appalachian Trail record, but to hike with her husband and daughter in every state while promoting her book that reflects on her love of hiking and her husband, called Called Again.
