Hainesport Endurance Run

The Hainesport Endurance Run is a 100-mile road ultra held in Hainesport, New Jersey. It takes place on a paved loop within Hainesport Township Park. The course is flat, fast, and certified, featuring a main loop of 0.9913 miles and an alternate certified loop of 1.2034 miles. Runners will complete this circuit multiple times. Beast Coast Productions organizes this event, which has occurred at least six times. Finisher numbers are modest compared to large marathons, with single-digit to a few dozen 100-mile finishers. This creates an atmosphere of focused endurance rather than a large gathering. Winning times have varied from the mid-16-hour range to over 23 hours for men, and from just over 18 hours to over 26 hours for women. This demonstrates how course conditions and race-day performance can significantly impact results on this straightforward course.
