If you are worried about getting a little dirty- this competition was not designed for you!. Many of the obstacles revolve around the mud. While each course is just a little bit different, some of the obstacles you might encounter include crawling through the mud underwires, scaling rope walls, traveling via monkey bars over pools of muddy water, flipping tires, and long runs over rocky terrains. Be prepared to cross the finish line covered in mud and sweat, and possibly even a few tears.
