Get dirty—then sudsy—on this 5K course that takes your typical mud run and turns it into a rave-worthy foam party. And with anywhere from 15 to 30 obstacles per race, it might just have a splash of Wipe Out in there, too. Expect inflatable walls, army crawls, cargo net climbs, and water slides. If you don’t get enough of the suds during the run—or you just want to clean the mud off of your body—the festival after-party boasts an awesome foam pit. Enjoy.
