The Next Loop Endurance Series - New England

The Next Loop Endurance Series is a loop based trail event held on a clearly marked 3.1 mile (5K) loop in Wrentham, MA. Runners begin a new loop on the hour and may stop after any completed lap; every completed loop is recorded and counts toward an official result.

Scoring records a time for each loop from the loop start to the finish line. Final rankings are determined first by loops completed and then by the combined time of those loops. Loop by loop timing provides athletes and crews with detailed split information for pacing and performance analysis.

The course is trail based and described as scenic, with a central start and finish area and an aid station available each hour. The format supports recovery and strategy between efforts and makes crew access straightforward.

Event logistics and entry fee are published as a flat price. Distances are cumulative by loops completed:

  • 1 loop = 5K
  • 2 loops = 10K
  • 4 loops = Half marathon
  • 9 loops = Marathon
  • 10 loops = 50K

The event is presented as suitable for a range of athletes, including runners training for longer distances and athletes who want to test pacing, recovery, and consistency over multiple hours. Visit the organization's website for the most recent information.
