From the Organizer
We are excited to share that this year we have added a 4 mile race option through the beautiful trails of RB Winter State Park. This distance is perfect for beginners who want to try trail running, as well as experienced runners who would like to enjoy a relaxed day on the trails with friends.
The Dam Half Trail Challenge has grown from a small race for hardcore trail runners into a popular, family-friendly event with a few hundred participants taking on the trails each year. Trail running has exploded in popularity, especially in central PA, where our diverse and high-quality races have even drawn national attention.
Profits from the races will be shared with the Mifflinburg Hose Company and the Middleburg Boy Scouts.
NOTE: To receive the neck gaiter and gloves you must register by Sunday, September 6. We need three weeks lead time for the supplier.
As always, great food, friends, and music after sharing the trails.
