Doesn’t it seem ironic that so many of these surprisingly popular adventure challenges and obstacle courses include large doses of mud, uh, in the desert? Natural hazards such as heat, sun, prickly things, poisonous creatures, rocky and unforgiving terrain all make sense given the environment. But mud in the desert seems slightly out of place.

Still, Toro Loco Challenge competitors will line up for the chance to test their mettle and get really dirty doing it. That must be the fun part as the race also features running, crawling, rope swings, zip-lining, hay bale battling, wall climbing, and other crazy hardships. Daunted? There’s a “leisurely” course, too. Kids and dogs are welcome; plus there are many non-painful activities in which to partake including live music and good food.
