A hardy test for trail runner of any level, The North Face Endurance Challenge New York winds along the western shores of the Hudson River and through the craggy foothills of the Catskill Mountains. Expect enough rocks and challenging terrain along the course to keep you engaged but not enough to prevent you from running the majority of the race. Trail running distances available are 50 Mile, 50K, Marathon, Marathon Relay, Half Marathon, 10K and 5K.
