Event Overview

The Next Loop Endurance Series - New England is a loop-based trail running event located in Wrentham, Massachusetts. The race format centers on a 3.1-mile (5K) trail loop that begins every hour on the hour. Participants complete a loop and then choose whether to start another loop or conclude their effort. There are no penalties or "did not finish" (DNF) statuses for stopping, as every completed loop is recorded as a successful result.

Distances and Scoring

The event allows runners to determine their total distance during the race based on the number of loops they complete. Participants can achieve specific milestones:

  • 5K: 1 Loop
  • 10K: 2 Loops
  • Half Marathon: 4 Loops
  • Marathon: 9 Loops
  • 50K: 10 Loops

Scoring is based on a transparent system that rewards consistency and pacing. The clock starts when a loop begins and stops when the runner crosses the finish line. Each loop time is officially recorded, and the final overall score is the combined time of all completed loops. Results are ranked primarily by the number of loops finished and then by the total combined time.

Course and Atmosphere

The race takes place on a scenic, clearly marked trail course. The start and finish lines are situated at a central base area, which serves as a hub for participants and their crews. An aid station is accessible to runners every hour at the conclusion of each loop. The environment is designed to be family- and crew-friendly, focusing on discipline and recovery rather than speed alone. Visit the organization's website for the most recent information.
