Harriman Big Bear Squatch Half Marathon

Saturday, October 19, 2024 • Tuxedo, NY • Course Map

Keep your eyes peeled during the Harriman Big Bear Squatch Half Marathon—you may find a Sasquatch lumbering through!

Whether or not Bigfoot deigns to make an appearance, you’ll join a committed group of “Sassquad” trail runners as you tackle this technical and challenging race. The well-marked looped course begins at Powerhouse Park in Tuxedo and carries racers on popular hiking trails through Harriman State Park.

While half marathoners of all levels are encouraged to experience the joy of trail running, this is not an easy course! With 1,000 feet of elevation gain in the first four miles alone, half marathoners will cumulatively climb over 2,200 feet.

Runners have 4 hours to complete the half marathon, but they must reach the check point at mile 3.5 by 10:30 AM. Two well-stocked aid stations with water, snacks, and fruit are available around mile 4.7 and 9.5, respectively. However, runners are also expected to carry additional water and aid—see the notes below.

The race is also a fundraiser to support the restoration of the historic Ramapo-Dunderberg Trail, on which portions of the half marathon are run. If you are interested in getting involved with this wilderness work, members of the New York-New Jersey Trail Conference—which maintains and protects over 2,000 miles of trails in these states—will be at the race and happy to chat.
