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! Join us at 10am on SUNDAY October 18, 2026 for this trail half marathon and 10K. All runners and hikers will experience non-stop trail beauty on this single loop course through Harriman State Park! Your race registration is directly helping the Trail Conference maintain and protect the trails that we will be enjoying on race day. Please visit our website for the complete details on this race, course maps, gpx files etc!

**We pushed back the start time to 10am so our friends from NYC can take the train directly to Tuxedo Station (across the street from the start/finish!)

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!
