Kismet Cliff Run North Conway, NH   Sep 13, 2026

The Kismet Cliff Run takes place every September amidst the rugged beauty of New Hampshire’s White Mountains. Choose either the Beast of the East Half-Marathon or Little Beast 5 Miler.

Little Beast is a five-mile race that navigates the roller coaster trails of Cathedral and Whitehorse Ledges. Twisting double track quickly gives way to steep, technical single track 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 has over 4,300 ft of vertical fun.

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.
