17 Mile Trail Run

From the Organizer

 


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. 

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. You will complete three counterclockwise loops followed by a final loop clockwise. You must check in at the beginning/end of each loop to have your time card punched.

Founded in 2017. This is NOT your average trail race. This trail is meant to test your strength and endurance. Seventeen miles with over 5000 ft. of elevation change, if you're not extremely careful there are many places where you can fall to your death or serious injury. No awards or medals. Race at your own risk. 

Course Description

Mile 0-1: from the start/finish out and back on 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. Once you reach the bottom you'll head north on smooth dirt trail along the river with beautiful views

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

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. 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

Miles 5-9 & 9-13 repeat miles 1-5. Last loop miles 13-17 you'll reverse your path. 

Aid Station

Mile 1, 5, 9, & 13     Fully stocked with water, sports drink, soda, candies, oranges, chips, pretzels and more! Feel free to leave your own personal supply stash, it will be safe and easy to access each loop.

*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) 

Email with complete information will be sent a week prior to event date to all registered runners, plz check your junk folder or send us a message if you can’t locate it.
