Run Amuck, the MCM's messiest mud and obstacle event, hosts 4,000 runners who face arduous obstacles and plenty of mud along a 4 mile course.
Run Amuck and the scaled down two-mile version of the course, Mini Run Amuck, is appropriately wild fun for rowdy runners (age 8 and up), outrageous athletes and fun-loving families
