South Mountain Reservation Stewardship & Advocacy



Runners are invited to register for the eighth Mayapple Trail Runs to be held on Saturday, May 20, 2017 in beautiful South Mountain Reservation in Essex County, N.J. Organized by the volunteers of the South Mountain Conservancy (SMC), with the support of the Essex County Parks Department, the races provide an informal but supportive trail race environment for runners who are up to the challenge of completing 10 or 20-mile distances, or ultra-marathons of 50 or 100 kilometers (31 and 62 miles).

All races start at the Locust Grove picnic area in Millburn. The course consists of a 10.5-mile east loop and 10.2-mile west loop through the forested 2,110-acre South Mountain Reservation. Following along the valley floor and the two ridges, the course includes long stretches of double-wide gravel roads, technically challenging, meandering single-track hiking trails with roots and rocks, and a short, half-mile stretch of pavement. It is a good combination of level paths, rolling hills, moderate climbs, and a few very steep ascents. The east and west loops total approximately 1,500 feet of ascent. The 50K and 100K runners start at 6:00 a.m. with the east loop, and continue alternating loops. Ten and 20-milers start this year at 9:00 a.m. (an hour later than prior years) on the west loop. The 10-milers only run the one loop; the 20-milers continue on the east loop which has some more rocky, technical trails.  (This year's 9:00 a,m. start allows runners to travel by train from Penn Station, NYC, to Millburn on New Jersey Transit's Morris-Essex Line.  The Millburn station is two blocks away from the Locust Grove starting point.)   

The parking space available at Locust Grove is limited.  It is strongly recommended that cars be parked across Glen Avenue at the lots between the First Aid Station and the Millburn Library.  Cars irregularly parked at Locust Grove will be ticketed.

A full description of the course is available HERE.  A map of the course can be downloaded from the link at the bottom of this page.

There are aid stations roughly every five miles where runners can have bags dropped off. At the stations, we offer electrolyte drinks and water, granola bars, pretzels and snacks. If you have a special request, please let us know; we will do our best. We are also still looking for volunteers to help out on the day of the race at the stations. As a final reminder, to manage the number of participants and administration, there are no race-day registrations. Registration ends on Friday, May 19th at 5:00 p.m.
