About the Squatchy Onesiefest
The Squatchy Onesiefest sends runners out in costume on the trails of Ramapo Valley County Reservation. It is a trail race, so expect roots and natural terrain rather than pavement, and the atmosphere leans toward the playful side of things. A portion of proceeds goes to a regional trail conservation group that maintains the land underfoot.
Runners are encouraged to show up in a onesie, and plenty do. The reservation is the kind of place where trails wind through woods, so arrive ready for uneven ground and leave the road shoes at home.

Finish-Time Stats
Going by the 2026 results, this is a small, friendly field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

The Squatchy Onesiefest has been held every year since at least 2020. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Sep 20, 2026.
