The 11 military-inspired obstacles are fun and unique but with just enough hell to keep your palms a bit sweaty. And the entire event is designed to be organic and eco-friendly. In fact, many of the obstacles will be recycled back into the earth. Think you’re a Dirty Girl? Well, here’s your chance to prove it. If that’s not reason enough, get dirty for a good cause.
