On a given sunny and relatively warm day in Philly, the main running trails are packed with runners, walkers, cyclists, dogs on walks, and others. One trail that is immune from crowds is Ben Franklin Bridge (yes the bridge).
For those who’ve never run it, the Ben Franklin Bridge is a surprisingly fun run. You enter the sidewalk entrance at 5th Street at Race and then begin a steady climb to the middle of the Delaware River and the state border. On the New Jersey side, there’s a subsequent steady downhill run as you cross the river.
