Climbing walls, ice baths, pools of mud, electric shocks?a Tough Mudder isn't your average event. Each 10- to 12-mile course contains 20 adrenaline-pumping obstacles designed to test participants' strength and endurance, just like most local DMV lines. Runners clamber on top of each other to scale the slick, sloping wall of Pyramid Scheme or squeal with shock as they plunge into the Arctic Enema, a plastic-lined dumpster filled with thousands of pounds of ice. They even endure shocks from a forest of live wires known as Electroshock Therapy.
But it's all worth it for the glass of beer at the end, plus the sense of camaraderie that develops among teammates. Many of those teammates go on to join the Mudder Legion, an organization for those who have participated in the event more than once. Tough Mudder also raises funds for the Wounded Warrior Project, which helps injured veterans transition to civilian life.
