The largest, and possibly oldest, mud run in the united states. It is a 6.2 mile all-terrain course with 36 Military Obstacles that include mud holes, walls, trenches, and more that require swimming, crawling, climbing, jumping, and sheer determination.

You WILL get absolutely muddy from head to toe and everywhere in between.

I have run this four years straight and have a blast doing it.
