Squatchy Onesiefest 5K

Join us on Saturday February 14, 2026 at the Ramapo Valley County Reservation for the SQUATCHY ONESIEFEST 5K! Come sporting your favorite onesie and get ready to make some trail running/hiking memories that will last a lifetime. We are proudly partnering with the New York-New Jersey Trail Conference for this event and will be making a donation to the Conference after the trail party ends. Please visit our website for the complete details on this race, course maps, gpx files etc! https://www.sassquadtrailrunning.com/onesiefest5k

This is a runner/hiker friendly event! Please sign up for the 5K if you plan on finishing the entire 5K distance (2 loops). Please register for the Fun Run if you are only up for one loop which is about 1.5 miles. Both events come with a medal at the finish line! We added the Fun Run option because we often have young kids come out for this Trail Party and they are not quite up to the full 5K course.
