U.S. ARMY TOUGH MUDDER

The Tough Mudder is a 10-12 mile (18-20 km), military-style obstacle course that challenges your strength, stamina, and camaraderie. More than one million competitors have taken on Tough Mudder, which is considered the most rigorous obstacle course series in the world.
The U.S. Army has partnered with Tough Mudder to encourage both Soldiers and Civilians to strive for the best, push the limit, and be relentless in the pursuit of success. Like the Army, Tough Mudder challenges you to overcome your fears and work with your teammates to accomplish a common mission.
