Denver, CO. We’re more than just a mud run. The real fun happens out on the playground — our 3-mile course packed with 20+ epic obstacles designed to both challenge and thrill Maniacs of all fitness levels, from couch potatoes to marathoners. The course opens at 9 a.m. but you’ll select a specific time to run when you buy your tickets. If you’re a late sleeper, that means you can wake up at noon, run at 1:45 p.m., and then party the rest of the day! Or if you’re the competitive type, join the 9 a.m. “Elite Heat” to race other speedsters for a chance to be crowned the winner! Each time slot is limited to just 200 Maniacs each, so grab your friends and reserve your spot before it sells out!
