From the Organizer
Nestled among rolling hills and dense forest, the Marilla Reservoir in Bradford, PA provides the perfect backdrop for trail racing.
With both 7 mile and 14 mile courses, the Marilla Trail Race offers the opportunity for beginners, hard-core trail runners, and everyone in-between to take advantage of Bradford's world-class wilderness.
Clearly marked trails take runners over a variety of terrain- gravel paths, dirt trails, and winding single track, with aid stations spread throughout. Except for a single road crossing, the 14 mile course is 100% off-road, and the same goes for the 7 mile route. While the courses are mostly non-technical, be prepared for intense elevation changes on the rolling hills and some winding single track. The race features state-of-the-art chip timing by Score This!!! and the historic covered bridge serves as the finish point for both distances. Then after the race, stick around for food, awards, and door prizes!
All proceeds from the Marilla Trail Race will go to benefit the Tuna Valley Trail Association and their ongoing commitment to the development and maintenance of trails locally in the Tuna Valley.
