Four Mile Run Trail
Named after Four Mile Run Creek, this seven miles-long asphalt trail (confusing, right?) passes through Shirlington and connects to the much longer W&OD Trail at multiple locations. Benches, trashcans, water, and restrooms are available at the numerous parks along the route every few miles, and the path is well marked. Because the portion of the trail running through Shirlington and Arlington is used by commuters heading into D.C., the route can get busy at rush hour. Cyclists should be aware that the Shirlington/Arlington portion of the path has several road crossings that may require a complete stop. The western portions of the trail are well-shaded, and mile markers are located along the route. The western portion of the trail does see some elevation change as the path runs parallel to the W&OD Trail. Cyclists, leashed pets, and pedestrians are welcome on the path, and playgrounds and parking lots are also available at the parks along the route.
