The Next Loop Endurance Series
October 31 All day
Wrentham, Massachusetts – The New England 50 Mile Challenge is a gritty, no-nonsense test of pacing and patience on a scenic 3.1-mile (5K) loop trail.
This is a continuous 50-mile trail race run alongside The Next Loop Endurance Series. Same fully stocked Start/Finish aid station every lap. Easy fueling. Simple logistics. All the support, every time through.
You’ll knock out 16 loops to hit 50 miles (trail measurements may vary slightly). A 12-hour cutoff keeps things moving and rewards smart pacing, with steady energy and a strong community vibe all day long.
You can stage gear at your vehicle or in the designated staging area. Pacers are welcome after 4:00 PM.
Chasing a PR? Eyeing your first 50-miler? Just looking for a long, honest day on trail? The New England 50 Mile Challenge delivers the full ultra experience, one loop at a time.
