Almost noon, half a mile into the RCT/NIH/GBT loop: I'm just inside the Beltway entering Walter Reed Annex and hear a rustling noise in the underbrush. It's a small three-point buck, pausing to stare at me. (Alas, I'm unarmed.) Today's weather is cool but a bit humid. I maintain a 2:1::jog:walk ratio for the entire 2h12m and feel (relatively) strong for the final four miles. Recently-flooded areas along Rock Creek Trail have been bulldozed clear; two-foot-high walls of drying mud channel the path under Connecticut Avenue.
