Marine Corps Marathon obstacle races, mud run, and OCR information, distance, cost, dates, calendar, discounts, obstacles, reviews, and more

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
