Washington D.C. and Bethesda, Md.
Length: 20.9 miles
Description: Up Wisconsin Avenue to Bradley Boulevard in Bethesda, out past the Beltway to Seven Locks Road, down to MacArthur and back into Georgetown.
Cons: After five miles or so, you leave the range of public transit, so bailing out gets a little hard. You’re reduced to running on the shoulder on Bradley, so be aware of traffic and avoid rush hour. Run where you can be seen.
Pros: You really gt out of town, you feel like you’re going somewhere and see a lot of different scenery. I love this one. There’s a convenience store near where Seven Locks Road meets MacArthur. If you go counter-clockwise, you get the uphill out of the way early.
Tricky Points: Negotiating the shoulder on Bradley Boulevard.
Afterward: If you drive, park near Mimi’s (5435 Mac Arthur Blvd NW) and get an sandwich (closed Sunday). Otherwise, options abound in Georgetown and all the way up Wisconsin Avenue.
