Williamsport, PA

Williamsport sits on the Susquehanna River in Pennsylvania's ridge-and-valley country, making it a hub for gravel cycling — the unPAved of the Susquehanna River Valley 321km event and Grinduro Pennsylvania showcase the region's networked farm roads and technical climbs. Runners have flatter options along the riverside, though the terrain rolls quickly once you head south toward the ridges; the Firecracker 5K is the local summer anchor race.
