Not sure this helps but - I spent a semester in DC and couldn't take my bike so I picked up running more seriously and did the Marine Corps Marathon. Definitely do that if you get a chance. Also, I don't know where you'll be living, but any run that involves a loop around Hains Point and past the Awakening statue/artwork can't be beat in my opinion.<br><br>
Oh, also make it a point of going to Eastern Market every Saturday morning.

Not a whole lot of open water swimming opportunities nearby, but there's always the bay, some further away lakes and lots of pools. I use the W&OD Trail for most of my biking/running, but then I'm out past Dulles.
