A sunrise run around the National Mall in Washington is the ultimate urban workout. Get out that early and you'll have the monuments, and the Smithsonian buildings practically all to yourself. If you're looking for a more serene option, head by the oft-overlooked Rock Creek Park and the tow path on the C&O Canal, which leads all the way to Harper’s Ferry, West Virginia.
