Boulder Beast

The Boulder Beast is a challenging trail running event held annually in Lock Haven, Pennsylvania, on Bald Eagle Mountain. The 2025 race marks its 10th year and offers two distances: a grueling 24-mile course with about 6,000 feet of elevation gain, and a 25K option for those seeking a shorter but still demanding experience. The course features rugged terrain including the famous boulder field and trails such as Goat Path, Lightning Ridge, and the Gorge Trail.

The start and finish are at the Castanea Township Fire Company picnic grounds, which provide ample camping and parking. The event includes a pre-race party and a post-race picnic, emphasizing a fun, community atmosphere. Strict cut-off times ensure runner safety on this tough, technical course.
