The members of The National Mud Runners Association strive to build challenging and entertaining obstacle courses with their medium of choice—mud—motivating participants to get fit while having fun and getting filthy. Each of their events attracts thousands of participants, who sprint across muddy terrain, climb over walls, and splash through muddy pools of water created by dinosaur footprints. After crossing the finish line, dirt-caked participants can amble into the event's postrace area to pick up their medal, grab a T-shirt, stroll around vendor booths, and dry off while soaking in live music. Committed to giving back to the community, The National Mud Runners Association donates the proceeds of each event to a charity.
