Runners follow an out-and-back course that winds alongside the Susquehanna River here eastern Pennsylvania at the River Towns Half Marathon, which starts and finishes near Danville’s Montour County courthouse. From there, runners make a few turns through town early in the race, and then follow a long, straight out-and-back along River Road to the turnaround point, which lies just past County Line Drive.
