The Frosty Fat Sass is a trail race for runners who love the cold (or runners who hate the cold but need to sign-up for an event because they need the accountability to keep running through the winter) and are ready for a physical and mental challenge! Join us on January 28, 2023 for the 6th annual Frosty Fat Sass! Runners can sign-up for a 5k, 3 hours or 6 hours. The 5K loop starts and finishes at the Turtleback Rock Picnic Area off of Walker Road in West Orange, NJ at the South Mountain Reservation. Funds raised at this trail party will be donated to the South Mountain Conservancy, an awesome local non-profit that preserves the South Mountain Reservation and provides great educational and recreational opportunities for the community! We have raised over $10,300 for the Conservancy since we started up in 2018!
