Tough Mountain Challenge
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.
