Tough Mudder

America’s Toughest Mudder is an 8-hour endurance challenge that starts at 12:00am midnight and ends at 8:00am. The goal is to complete as many 5-mile loops as possible - half and quarter loops don’t count. But while this event is a race, camaraderie is ever present on the course. Television station CBS has been there to capture all the action in this six event series.
