The Dam Half
Mifflinburg, United States • 27 Sep 2026
Trail Running in RB Winter State Park
The Dam Half and Dam 4 mile-ish are trail running events held within the grounds of RB Winter State Park in Mifflinburg, Pennsylvania. This event has transitioned from a small gathering for specialized runners into a larger community event that hosts several hundred participants annually. The race utilizes the trail systems of central Pennsylvania, an area recognized for its variety of trail racing opportunities.
Participants can choose between two distinct distances:
- 13.1 miles (The Dam Half)
- 4 miles (The Dam 4 mile-ish)
The 4 mile option is designed to accommodate those new to trail running as well as experienced runners seeking a less intensive day on the trails. The event features post-race activities including food and music for participants. Registration includes specific commemorative items, such as a neck gaiter and gloves, provided the registration is completed by the designated early September deadline to meet supplier requirements.
Financial proceeds from the event are distributed to local community organizations, specifically the Mifflinburg Hose Company and the Middleburg Boy Scouts. The races emphasize a social atmosphere within a natural park setting. Visit the organization's website for the most recent information.
