Prepare for a true test of grit and a feast for the eyes at the Big Bear SquaTCh South, a demanding trail race taking place on October 18, 2026, in scenic Tuxedo Park, NY. Hosted by Sassquad Trail Running and the New York-New Jersey Trail Conference, this event offers both a Half Marathon and a 10K, guiding runners through the rugged, technical trails of Harriman State Park. The Half Marathon boasts over 2,200 feet of cumulative elevation gain, with a challenging 1,000 feet packed into the initial four miles, while the 10K presents over 1,200 feet of vertical ascent. Expect a course defined by rocks, roots, steep climbs, rocky cliffs, and even a short scramble, all while enjoying the breathtaking peak fall foliage of the Hudson Valley. This isn't just a race; it's a "true northeast mountain race" and the second most challenging in Sassquad's Mountain Madness Series, known for its non-stop trail beauty and rewarding sweeping views.

Runners and hikers will navigate a single-loop course, with race registration directly contributing to the New York-New Jersey Trail Conference's vital work in maintaining and protecting these cherished trails. Typical race day conditions in mid-October offer crisp autumn air, with highs around 65°F and lows around 46°F, and only a 13% chance of precipitation, creating ideal cool weather for tackling the challenging terrain. Aid stations are strategically placed, with the Half Marathon featuring stops at miles 4.75 and 9.5 offering water, Skratch, bananas, granola bars, and more, including gluten-free options. The 10K also includes an aid station at mile 2.5. The race starts and finishes at Powerhouse Park, conveniently located across from the Tuxedo Station, making it accessible for those traveling by train.

The Big Bear SquaTCh South is more than just a race; it's a "trail party" experience, fostering a supportive "Squatchy" community. This event has a reputation for selling out quickly, a testament to its compelling course and welcoming atmosphere. For those seeking a truly challenging and scenic trail adventure that also gives back to the trails we love, the Big Bear SquaTCh South promises an unforgettable day in Harriman State Park.
