    The flowy, fast, and fun trails at Schaeffer Farms are wonderfully maintained and offer twisty single-track, stream crossings, log ramps, a few hills, and open farm field running. Moderately technical with some rocky and rooty sections, these race courses begin and end at the beautiful Button Farm Living History Center off Black Rock Road.

    Charity partnership

    We are raising funds and awareness for two wonderful non-profits in Montgomery County, Interfaith Works and Button Farm Living History Center. The goal of the charity partnership is to first and foremost to raise awareness of the services that these wonderful organizations provide in our area. In addition, we hope to raise funds that will directly support their efforts. Please consider making a donation when you register.
