About

The Event

At approximately 5k in length it may look like an easy hike, but you'll change your mind as soon as you take off running up a mountain under an arsenal of snowguns or scrambling through the mud. Tough Mountain Challenge is a timed event, but it's not about whether you finish first or last—it's about testing yourself and pushing your limits, then celebrating your accomplishment once you cross the finish line. Plus, Tough Mountain Challenge limits the number of competitors in the event and in each heat, so you won't feel crowded or rushed on the course. It might be the most fun you'll ever have while also considering crying.
