The Montour Trail is fantastic for running and biking long distances. The Trail Council does a fabulous job of maintaining the conditions as well as raising money to provide signage and mile markers. My only wish would be for a clean public bathroom facility somewhere, but perhaps that will be a possibility in the future! This is one of the only trails in Pittsburgh with a gravel surface which is much kinder on your knees than pavement and certainly worth the occasional rock in your shoe frustration.
