These routes seamlessly combine many of DC’s popular shorter trails to create extended paths through and around large chunks of the metropolitan area. These options are popular with recreational walkers, joggers, cyclists, and commuters, so they tend to be fairly populated at most times of the day. The terrain is generally even and maintained on each route, excepting the portions of the Interior Northwest DC Trail that are on unpaved wooded trail systems. With the exception East Potomac Park, which is suitable for most any kind of workout, these paths—particularly the lengthy routes—are good options for long distance runs and daily maintenance workouts.
Since these route options can be extended (and shortened) according to your desire, it is recommended that runners plan their workouts with maximum safety in mind. Always carry the necessary amounts of water (or sports drink) and nutrition, particularly since some of these route options stretch beyond 20 miles. Likewise, runners should wear appropriately reflective gear, and they should carry supplemental lighting with them at all times. Finally, runners are advised to carry some form of identification, a cellphone, and taxi money when completing a lengthy workout.
