Are you ready to get dirty? Based at Sunday River Resort in Newry, Maine, this race might be the most fun you'll ever have while also considering crying. 

Tough Mountain Landslide Obstacle

What is TMC?

The Tough Mountain Challenge is an adventure 5K race that combines alpine terrain with natural and manmade obstacles. 

Running through snowguns and scrambling in the mud will push your limits. But, it's not just about finishing first or last; it's about conquering the course and celebrating your triumph. 

It might be the most fun you'll ever have while also considering crying.
