Harriman Big Bear Squatch Half Marathon

Lace up for an unforgettable trail adventure at the Harriman Big Bear Squatch Half Marathon on October 18, 2026, in Tuxedo Park, NY. This challenging 13.1-mile race, presented by Sassquad Trail Running and the New York-New Jersey Trail Conference, plunges runners into the rugged, single-loop trails of Harriman State Park, renowned for its non-stop beauty and vibrant peak fall foliage. Prepare for a true Northeast mountain experience with approximately 2,200 feet of cumulative elevation gain, including a stout 1,000 feet within the first four miles. The course is highly technical, featuring abundant rocks, roots, steep climbs, descents, and even a short scramble, making it a demanding yet rewarding endeavor for experienced trail runners.

The Harriman Big Bear Squatch Half Marathon isn't just a race; it's a "Sassquad" tradition with a mission. Your participation directly supports the New York-New Jersey Trail Conference's vital work in maintaining and restoring trails, including portions of the historic Ramapo-Dunderberg Trail. The race kicks off at Powerhouse Park, conveniently located across from the Tuxedo Train Station, with a later 10 AM start to accommodate commuters. Aid stations at roughly mile 4.7 and 9.5 offer water, bananas, granola bars, Skratch, and other provisions, though runners are expected to be self-sufficient, carrying a charged phone, water, a whistle, and at least 200 calories. With typical race day conditions seeing highs around 65F and lows around 46F and a 13% chance of precipitation, expect crisp autumn air perfect for trail running.

This event is known for its challenging nature and the spectacular Hudson Valley views that reward every hard-earned climb. With a 5-hour time cutoff and intermediate cutoffs requiring a roughly 23-minute per mile pace, it's a course designed for those ready to embrace the mountain. Keep your eyes peeled for a Sasquatch while you're out on the trails; whether or not Bigfoot makes an appearance, the Harriman Big Bear Squatch Half Marathon promises an unforgettable journey through breathtaking wilderness.
