As (relatively) easy as Wednesday’s mile was, this morning’s was unpleasant. My legs and torso were heavy, my breathing was desperate, and it was sheer bloody-mindedness that enabled me to get as far as Leopold Street for my break-stride (still only one, though). Time was 11:03, which may suggest that I set too ambitious a stride early and burned out — so that my final time wasn’t that much worse than usual, but the experience of running was more frustrating.
