The Arc of York and Adams Counties holds its annual Rail Trail 10-Miler to benefit individuals with intellectual and other disabilities in south central Pennsylvania. The race starts at Liberty Christian Fellowship Church in Seven Valleys, PA and runs ten gentle, downhill miles one-way north along the scenic York County Heritage Rail Trail, passing through the oldest operational train tunnel in the nation, and finishing on the Rail Trail near Princess Street in downtown York, PA. After the run, post-race refreshments and entertainment will take place at the Agricultural and Industrial Museum (directly across the street from the finish line).
