Race logistics
The course is a continuous loop of 4.0 miles, largely flat with one minor speed bump. The route uses the New Boston Rail Trail along the Piscataquog River to a turnaround at Lang's Station, then returns and follows a gravel service road around the fairgrounds. Loop tracking is managed at the Start/Finish with chipped bibs; bib numbers must be visible on the front of the body. A central aid station at the Start/Finish supplies water, electrolyte drinks, sodas, fruit, gels, and other food; 6/12/24/30 hour runners will have lunch/dinner options, and 24/30 hour runners receive breakfast. Pacers are not allowed in the 6 hour race; 12, 24 and 30 hour entrants may use one pacer after dark (starting at 5:00 PM). Dogs are not allowed on the grounds. Tents, small pop-ups, canopies, and RVs are allowed; quiet hours are 10:00 PM to 7:00 AM. Runners in the 12, 24 and 30 hour events must supply their own headlamps.
