Bear Brook Trail Races

Allenstown, United States • 20 Sep 2025

The Bear Brook Trail Races, held in Allenstown, New Hampshire, showcase the scenic beauty of Bear Brook State Park with its diverse trails, including single track paths, steep hills, and blueberry fields. The event offers three race distances: a 10K following "Mindy's Loop," a Half Marathon, and a Marathon, with the marathon course consisting of two laps of the half marathon route. Runners navigate using GPX files, as the course has minimal markings. Aid stations provide water, Tailwind powder, and food, but participants must bring their own hydration containers due to a no-cup policy aimed at minimizing litter. Pets and pacers are not allowed.
