About the Event

Embrace whimsical winter fun on the trails at the Squatchy Onesiefest 5K in Mahwah, New Jersey on February 14, 2026. This unique "trail party" hosted by Sassquad Trail Running invites runners and hikers of all ages to sport their favorite onesie and tackle a flat, scenic 5K (two loops) or a shorter 1.5-mile fun run around Scarlet Oak Pond. Feel the joyful, community-focused atmosphere of an event that prioritizes laughter, costumes, and family-friendly adventure over fierce competition, all while supporting the vital trail maintenance work of the New York-New Jersey Trail Conference.

Experience the perfect introduction to trail running on the wide, non-technical gravel paths of the Ramapo Valley County Reservation, where road shoes are sufficient and the only requirement is a festive attitude. With a 10:00 AM start, check-in from 9:15 AM, and a handcrafted medal for every finisher, the day is designed for maximum enjoyment and inclusivity. The event proudly offers hardship entries, generous family and youth discounts, and special recognition for top finishers who complete the course in their onesies. Secure your spot for a morning of lighthearted exercise, squatch-hunting, and community spirit that proves trail running can be an absolute blast.
