Course and logistics
The route follows the Nipmuck Trail and runs alongside the Fenton River for much of the course. The trail includes several small bridge crossings, fields and woods, and a climb to a 50 ft cliff. There are three water stops along the trail and support at three road crossings. The course was modified to bypass a missing iron bridge and a lollipop at the turnaround was removed to keep the overall distance similar. Timing will not be recorded after the official race cutoff and assistance is provided to return runners to the start after the cutoff.
