About this race
🏃♂️ Race Overview
Traversing beautiful viewpoints along the Hudson River from New Jersey to New York and back again, the Interstate 17 Trail Run delivers amazing scenery as it tests your physical prowess.
🔄 Race Structure
- Loop Format: You will run four times on a four-mile loop of rugged technical trails after a mile out and back on a closed road to separate the field of runners for safety.
- Loop Direction: You will complete three counterclockwise loops followed by a final loop clockwise.
- Timing: You must check in at the beginning/end of each loop to have your time card punched.
- Race Safety: Founded in 2017, this is NOT your average trail race. This trail is meant to test your strength and endurance.
🌄 Course Description
- Mile 0-1: From the start/finish out and back on the road.
- Mile 1-2: Heading south along a semi-technical rock-strewn dirt trail which leads to a steep long descent on rocky uneven jagged stairs and switchbacks.
- Mile 2-3: A boulder-filled rock scramble where you'll need to use your hands to navigate at certain points ends with a singletrack dirt trail with short yet steep ascents and descents along the river.
- Mile 3-4: Singletrack dirt path takes you directly back into another rock scramble, however this portion is much more runnable, ending directly on the shore of the river.
🏞️ Final Legs of the Course
- Mile 4-5: As you continue along the rocky shore trail you'll encounter the beautiful waterfall signaling your time to ascend the cliff using various switchbacks and staircases.
- Aid Station: You will find checkpoints at miles 1, 5, 9, & 13, fully stocked with water, sports drink, soda, candies, oranges, chips, pretzels, and more!
- Personal Supplies: Feel free to leave your own personal supply stash, it will be safe and easy to access each loop.
- Safety Recommendation: Due to distance between aid, we highly recommend carrying your own hydration supply.
