About Hairy Gorilla Half Marathon & Squirrelly Six Miler

A Halloween-themed trail race that takes runners through the foothills of the Catskill Mountains in eastern New York State, the Hairy Gorilla Half Marathon and Squirrelly Six-Mile Run have something for everyone when it comes to trail running races — plenty of challenging hills, deep woods forest lands to run through, wet and inclement weather conditions at times, and plenty of natural beauty surrounding you as you run.

Organizers caution that this isn’t a race you should be looking to set any personal records at — the course will take much longer to complete than a road race.

Thacher State Park



The course follows an out-and-back loop course through John Boyd Thacher State Park, whose Helderburg escarpment is known as one of the richest fossil-bearing rock formations on earth, and whose trails offer runners, hikers and backpackers panoramic views of the nearby Hudson and Mohawk River valleys.


The first 6 miles
The race begins with a 600 meter loop around field and then heads north along the Escarpment towards Hailes Cave Pavilion.
It then runs on the wide grass field parallel to the Long Path before joining the Long Path and running a loop in the north section of the park.
The first 1.25m is the same as the final 1.25m.

The remaining 7+ miles
The second half of the course begins with a beautiful stretch along the fence line of the park. It then heads up the hill by the Paint Mine trailhead to Beaver Dam Rd.
After that nearly mile long ascent, the rest of the race is mostly flat or downhill. There are many beautiful sections in this part that have never been part of this event before.
