One of the largest urban green spaces in the country, Philadelphia’s Fairmount Park consists of more than 9200 acres of trails, woodlands and wetlands. The park is divided into east and west sections, divided by the Schuylkill River. There are many options for runs here, so it’s not easy to plot one particular route. One good option is to start near the Philadelphia Museum of Art and head north along East Fiarmount Park. You can follow the trail along the river, or enjoy some of the interior trails. Then cross one of the bridges and run back alons West Fairmount Park, again along the river or one of the interior park trails or roads. Crossings are at Girard (1.2 miles), Strawberry Mansion (3 miles), or Falls Bridge (4.25 miles).
