July 21, 2012 ~ Sunday River, Maine

If you just want to jump in some mud, climb over a few walls, or make laps on a course for several miles with 10,000 other people, you'll find plenty of mud runs, military-style obstacle courses and endurance races across New England. If you want to suffer for hours or risk death, you can find those races too. But if you’re looking for something different – a fun event to test yourself and push your limits both physically and mentally – welcome to the Tough Mountain Challenge.

Now in its third season, the Tough Mountain Challenge is a unique adventure obstacle race born in the mountains of Maine that tackles the alpine terrain of Sunday River ski resort. You won't die. You may not even bleed. But trust us - it's no walk in the park. After running 5k in the mountains, under an arsenal of snowguns, crossing ravines and climbing through natural obstacles - you'll feel it by the finish line.

And when you cross that line you’ll be in the middle of an all-day party complete with a DJ, barbecues, a beer garden, a free Mini Mountain Challenge for kids, chairlift rides, ziplines, and more - all ending with a post-race party.

The Tough Mountain Challenge is limited to 2,000 competitors to ensure a great experience for everyone. Register now to secure your spot!

Spectators are welcome (and free)!
