Welcome to DC and enjoy the run. For Crystal City – there are a number of bars (Crystal City Sports Pub, Buffalo WW, etc) – but they may all be swamped due to folks in town for the run. So you may want to venture a bit away from the concentration of hotels that are close to the start line. Maybe some of the bars on the Orange Line: Court House – Ireland’s Four Courts, Summers; Clarendon – American Tap Room, Hard Times Cafe – or you can venture into DC.
