Big Bear SquaTCh South 13.1M, 10K

Sassquad Trail Running and the New York-New Jersey Trail Conference are proud to present the Big Bear SquaTCh South at Harriman State Park in Tuxedo, New York on Sunday October 19, 2025. All runners and hikers will experience non-stop trail beauty through Harriman State Park! Your race registration is directly helping the Trail Conference maintain and protect these trails. (The capitalized "TC" in SquaTCh stands for "Trail Conference"!!) This event WILL sell-out before race day so register early to avoid being added to the waitlist!

We are proud to be co-hosting this trail party with our friends at the New York-New Jersey Trail Conference! Please consider donating by using the add-on feature during registration. The NYNJTC maintains and protects over 2,000 miles of trails in New York and New Jersey.

The Half Marathon has 2,200+ ft of cumulative gain; There is 1,000 ft of gain in the first 4 miles! The 10K has over 1,200 ft of vertical gain. Both courses are very technical route, which means that there are a lot of rocks and roots. There are steep climbs, rocky cliffs and even a short scramble. We want to emphasize that this is a very challenging course and very different from our other events! If we have rain (or snow?), the course will be extra challenging. All of that being said - this is a beautiful course! Your hard efforts will be rewarded with sweeping views as you get to enjoy peak foliage in the Hudson Valley. Since we started hosting this event in October, we have always lucked out with amazing fall colors!
