The Kismet Cliff Run take place every September amidst the rugged beauty of New Hampshire's White Mountains. Choose either Little Beast or the Beast of the East Half-Marathon, and know you will be challenging yourself for a good cause.
Little Beast is a five-mile race that navigates the rollercoaster trails of Cathedral and Whitehorse Ledges. Twisting doubletrack quickly gives way to steep, technical singletrack as you take on the first of two tough ascents. The subsequent descents, with miles of Conway granite all around you, will challenge even the best technique. Fortunately you won't worry about your PR as you take in the beauty of Echo Lake State Park and the White Mountains.
The Beast of the East Half-Marathon takes the Little Beast Course, and adds a stupendous loop over North Moat Mountain via the incredible granite Red Ridge. As you grind your way up the 2,000 foot climb, you will have time to take in the amazing views. However you will be fully exposed to any inclement weather, so be prepared!
The Beast is easily a contender for "toughest half-marathon" anywhere, but that label pales in comparison with the stirring views to the Presidential Range, the Pemi Wilderness and beyond.
