What could be more exciting than a group of girlfriends hopping, climbing, slipping and sliding through 12 challenging obstacles while decked out in extravagant costumes? The Dirty Girl Mud Run 5k has become one of the most anticipated non-competitive women only adventure runs to date and it is all because of its reputation for building friendship, camaraderie, having fun, enjoying some laughs and getting downright muddy.
