The SMR Mayapple Trail Runs, held annually in South Mountain Reservation, Millburn, NJ, offer a variety of trail race distances including 50 miles, 50K, 20 miles, 10 miles, 5 miles, and a Kids 1-Mile Run. The event features three main loops—east (10.5 miles), west (10.2 miles), and a challenging 5-mile counterclockwise loop—through forested terrain with a mix of gravel roads, technical single-track trails, rolling hills, and steep climbs totaling about 1,500 feet of ascent. Aid stations are placed every five miles, providing hydration and snacks. The race supports the South Mountain Conservancy’s mission and is volunteer-run, with convenient access via NJ Transit from NYC. Visit the organization's website for the most recent information.
