Tough Mountain Challenge
A Wicked Dirty 5k
July 24-26, 2020
If you want to run 10 miles in the company of 10,000 other people and wait in half-hour lines at each obstacle, you'll find other events where you can do just that. If you want to suffer for hours and risk life and limb, you can find those races too.
But if you're looking for something different - something as fun as it is tough without the ego and the crowds - welcome to the Tough Mountain Challenge, an adventure obstacle race that tackles the alpine terrain of Sunday River with over 20 fun, challenging, and muddy obstacles.
This event sells out every year and registration is open for 2020. Be sure to join the party at Friday night's free Big Ass Bash, cheer on your friends Saturday, and sign your kids up for Sunday's Mini Mountain Challenge. Registration for Mini Mountain 2020 will open soon.
