I sat down with Nick Arganbright - a budding legend in the ultra-endurance world. In the last 4 months, he's completed a 50-mile race, the Marathon Des Sables (look it up - seriously), and most recently, the Spartan Death race, of which less than 10% ever finish (he & 3 others finished).
He shared his great perspective on what got him through it and all the craziness they had him endure over the course of 70 hours STRAIGHT of work.
