Get ready for a challenging 17-mile trail adventure in Closter, NJ that showcases stunning Hudson River views while pushing your limits with over 5,000 feet of elevation gain. You'll tackle a one-mile road section followed by four loops of rugged, technical terrain (three counterclockwise, one clockwise), checking in at the start/finish after each loop to track your progress. This demanding course features serious exposure and technical obstacles, so careful footwork is essential—there are no awards or medals, and you run entirely at your own risk.
