Course and aid stations

The course begins with a one-mile out-and-back on a closed road to separate the field for safety. Runners then complete four laps of a four-mile loop: three laps counterclockwise followed by a final lap clockwise. Runners must check in at the start and end of each loop to have a time card punched. The route follows viewpoints along the Hudson River from New Jersey to New York and back and includes rugged, technical trails with over 5000 feet of elevation change. Specific features listed include rock-strewn singletrack, boulder scrambles that may require using hands, steep descents with jagged stairs and switchbacks, shoreline sections, and a cliff ascent using switchbacks and staircases. Aid stations are located at miles 1, 5, 9, and 13 and are described as fully stocked with water, sports drink, soda, candies, fruit, and snacks. Personal supply stashes are allowed and organizers recommend carrying personal hydration, noting handhelds may be cumbersome. Visit the organization's website for the most recent information.
