About this race
Event 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 Format
- Loop Structure: 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.
- Counterclockwise Loops: You will complete three counterclockwise loops followed by a final loop clockwise.
- Check-in Requirement: You must check in at the beginning/end of each loop to have your time card punched.
- Race Safety: This is NOT your average trail race. This trail is meant to test your strength and endurance.
Course Details
- Starting Point: Mile 0-1: from the start/finish out and back on road.
- Technical Challenges: 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. Once you reach the bottom you’ll head north on smooth dirt trail along the river with beautiful views.
- Rock Scramble: 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.
- River Path: 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 Leg
- Waterfall Ascent: 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.
- Return to Checkpoint: Once you reach the top it’s a short trip south through wide cross country skiing trails back to the checkpoint/aid station at the start/finish area.
- Repeats: Miles 5-9 & 9-13 repeat miles 1-5. Last loop miles 13-17 you’ll reverse your path.
Aid Station Information
- Locations: Mile 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.
- Hydration Recommendation: Due to distance between aid we highly recommend carrying your own hydration supply (handhelds may be cumbersome at times you may require both hands free).
- Event Communication: Email with complete information will be sent a week prior to event date to all registered runners, please check your junk folder or send us a message if you can’t locate it.
