Bear Brook Trail Races

Bear Brook Trail Races take place at Bear Brook State Park in Allenstown, New Hampshire. The event offers three trail races: Marathon, Half Marathon, and 10K (the 10K follows Mindy’s Loop). The Marathon doubles the Half Marathon route.

Runners encounter diverse terrain—from beautiful single-track through blueberry fields to steep uphills—showcasing the park’s natural beauty. For 2025, the race is GPX-only with minimal course markings; entrants download and navigate with the provided GPX, with maps released in advance. Aid stations are well stocked with food, water, and Tailwind; no cups, no pets, and no crews/pacers.

Marathon has a strict 9-hour cutoff. Visit the organization's website for the most recent information.
