This Event Took Place Sat. Feb 17, 2024


"You guys should put on an event where everyone has to wear a onesie."

"That sounds like an AMAZING idea."

"It should be in the dead of winter."


And so the Squatchy Onesiefest was born! Is it a ridiculous idea? You bet it is. Won't it be really cold in February? Yup, that's why you need to wear a onesie. Do they even make onesies in my size? Of course they do!!

Join us on Saturday February 8, 2025 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!


This is a runner/hiker friendly event! We LOVE having families come to our events, so make sure you register your kiddos to join in on the fun.

10AM Start Time - please check-in between 9:15am-9:45am

Please allow a few minutes to walk from the Reservation park parking lot over to the NYNJTC Headquarters. All participants receive a handcrafted medal at the finishline. Awards for top 3 male, female and non-binary (must be wearing a onesie to earn post-race awards!)


This trail party starts and finishes at the NYNJTC Headquarters. When you get to the park, please park in the PARK PARKING LOT. The small lot at Headquarters is reserved for NYNJTC staff only. There is a short path through the woods that connects the two lots. We will have check-in at the NYNJTC Headquarters so you can hang out there before and after the race. There are real restrooms in the building too (#winning).

The "lollipop" course is 1.60 miles long. All runners and hikers will squatch the full course twice to complete the 5K. All runners/hikers need to come all the way back to Headquarters after the first loop so our timing system records your split.

With the exception of the small trail that connects Headquarters to the park, the entire lollipop course is a very wide gravel trail. The small trail that connects you to the park is a single track and is less than .20 mi long. The scenic loop goes all the way around Scarlet Oak Pond; it is not technical and it is very flat (only 112 ft of gain)!

And make sure to keep track of little Westley and Buttercup before during and after the race. We only have 1 search-party and they're already out there looking for Sasquatch.

Q: What's the weather like in Mahwah, NJ in February?
A: I'll explain and I'll use small words so you'll be sure to understand, you warthog faced buffoon. It will be cold. Probably. Maybe. It could be warm. Check the weather before the race and dress appropriately.

Q: This will be my first trail race. What do I need to know?
A: Inconceivable.

Q: No really, it is my first trail race! Any advice?
A: You fell victim to one of the classic blunders—the most famous of which is, “Never get involved in a land war in Asia”—but only slightly less well-known is this: “Never go against a Sicilian when death is on the line”! Ha ha ha ha ha ha ha! Ha ha ha ha ha ha ha! Ha ha ha…........ But seriously, we are SO EXCITED that you are choosing a Sassquad event for your first trail race! This is the perfect intro event as the trails are not very difficult. Come ready to have a great time and meet some awesome people!

Q: What food will you have at the aid station?
A: MLT – mutton, lettuce and tomato sandwichs. And miracle pills. The chocolate coating makes it go down easier. But you have to wait fifteen minutes for full potency. And you shouldn’t go in swimming after, for at least an hour.

Q: Ummmm???
A: No miracle pills. But we will have water (please BYO-cup/bottle!!) pre-packaged single-servings snacks for after the race.

Q: I could get lost in a brown paper bag. Will the course be marked?
A: We will have bright colored ribbons along the course and plenty at all of the turns.

Q: I don't want to run, are there any volunteer opportunities?
A: Yes! We always need Sassy Volunteers! Click the "Volunteer" button at the top of the page!

Q: Are there restrooms at the start/finish area?
A: There are restrooms in the Reservation Parking Lot. Use those before you check-in!

Q: Me and my friend aren't registered for the race, but we're still planning on coming to run. We won't eat from the aid station or take a medal or swag. This is okay, right?
A: NO THIS IS NOT OKAY. This is called being a "race bandit" and it is stealing. Not paying for a race and running the race is stealing from the race organization (even if you're not taking food or swag). Don't do this at a Sassquad trail party or ANY other race. It's not okay. And if you hear about someone else doing this, call them out. If you bandit a race, you will be banned from registering for any of our Sassquad events.


Like many other race organizations, we do not offer refunds for our events. Please take the time to double check your calendar before registering for a Trail Party. Please understand that we do not offer refunds under any circumstances. If you notify us via email (not through social media, text or phone call) more than 45 days from the date of the Trail Party, we will extend a deferral to any of our events that fall within one calendar year of the Trail Party that you were registered for. If you sustain an injury less than 45 days from the race date, we will extend a deferral if you come to that race to volunteer for at least 4 hours. The race credit is the amount that you paid for the race (not including UltraSignUp fees) so you will need to cover any difference in fees; refunds will not be issued if the deferred event costs less than your race credit. You can only defer one time so please doublecheck that you can make the race you're deferring to.


Join the Sassy Volunteer Squad! We need help with check-in, sweeping the course and cleaning up. Are you registered for a race that requires volunteer hours? We can sign-off on the hours that you log at the event! Volunteer to provide delicious food for the runners and we can sign-off on your prep time! We love our volunteer team and we are always looking to add more sassy members to the Volunteer Squad! Email us at if you'd like to volunteer!
