Rain or shine — because you’ll be getting muddy anyway — the Dirty Girl Mud Run will hit up Columbus. The women-only national mud run series consists of an untimed obstacle course with super irreverent challenges (there is a “Utopian Tubes” Tunnel Crawl and a “PMS” Mud Pit). Every obstacle is optional and all ages and athletic abilities are welcome. Just no dudes. Crazy team uniforms are encouraged. And if that wasn’t enough to make you want to sign up right now: Cancer survivors run for free. A portion of all the $75-per-runner registration fees goes to the National Breast Cancer Foundation. The Dirty Girl Mud Run will be in Columbus on Saturday, June 1. Location TBA. Start working on your sexual organ pun team name now!
