The LOCO Marathon course is two loops of 13.1 miles. The first 10 miles travel along all rural roads with plenty of shade and scenic vistas.
The elevation of the course starts at a base of 60 feet and has a maximum elevation change of less than 100 feet. The first three miles are rolling and take you on a shaded road to Lee New Hampshire. There is then a nice almost totally flat section on Wadley Falls road until mile 5.
Next is a gentle incline on Campground Road into Epping. Then runners travel through Newmarket on Grant Road with a small hill, then onto Bald Hill Road. Bald Hill road is gently rolling and “Bald Hill” is off to your right. By mile 10 runners exit to the Rail Trail.
The last 3 miles of the Rail Trail are covered with cinder and crushed gravel. It is relatively flat with very gradual inclines. It passes beaver ponds and unspoiled woodland. The trail can support 2-3 runners across in most locations and has good footing.
