The Frosty Fat Sass is a Trail Party for runners and hikers of all ages and paces. Runners and hikers 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!
