Join us on Sunday October 5, 2025 for a 5K (3 loops) 3 hours or 6 hours. The 1 mile loop with 300 ft elevation gain starts and finishes at the Locust Grove Picnic Area off of Glen Ave in Millburn, NJ at the South Mountain Reservation. This isn’t just any Trail Party… It’s a battle for good. We’re donating 100% of the profits to Bigger Than The Trail, a nonprofit bringing hope to the galaxy by offering free mental health therapy to those in need.
