The Worlds Toughest Mudder is an obstacle course race that is a test of mental and physical endurance. Devin Nelson is my guest this week. He is both an ultramarathon runner and tests his will against the 24 hour challenge of the Tough Mudder.

The Tough Mudder community is much like the trail running community in the way participants help and encourage each other as they compete against the course. Caution, trail runners! This episode might give you ideas for new challenges.
