Big Bear SquaTCh South : Harriman State Park, Tuxedo NY
Big Bear SquaTCh South is a trail half marathon and 10K held in Harriman State Park on October 18, 2026. The event is cohosted with the New York New Jersey Trail Conference and registration proceeds support trail maintenance.
- 13.1M (half marathon) approximately 2,200 ft elevation gain
- 10K approximately 1,200 ft elevation gain
Both routes follow technical singletrack with many rocks and roots, steep climbs and descents, and one short scramble. The half marathon gains over 1,000 ft in the first four miles. Course markings use bright pink or reflective ribbon and large directional arrows at turns.
There is a five hour finish cutoff for both events. The half marathon includes two on course cutoffs and participants are expected to maintain set paces to meet those cutoffs. Aid stations: the half marathon has two aid stations with water and packaged food; the second station includes Skratch hydration, pb and j, fruit, and gluten free options. The 10K reaches the second aid station via a short out and back. Each aid station carries a stocked first aid kit; an AED is available at event headquarters.
The start and finish are at Powerhouse Park in Tuxedo. Parking uses the commuter lot with a small fee. Participants should note there are no restrooms on course and should carry required gear such as a charged phone, hydration, whistle, and a GPX course file.
