Episode two of the Out and Back podcast drops today featuring thru-hiking legend the The Real Hiking Viking. In this episode, meet free-spirited and fun-focused Thomas Gathman, who picked up the Viking trail name due to his Norse-like beard and his warrior status as a former Marine Scout Sniper. Viking served two combat tours in Iraq before coming home, selling all his possessions in 2013, and hiking more than 20,000 miles on America’s longest trails. Tune in to hear Viking’s story about how he turned from sniper to pro hiker and never looked back.
