It was the breathing this morning — ragged and desperate — partly (I expect) because it’s colder this morning, and partly because I set a more demanding pace for myself. This reminded me how little I like running. Still, it had a positive result, as I pushed my mile (without break) time back down to 10:39. I don’t think I’ve combined a full-mile run with that good a time, and I don’t care to look back at previous times to check. However you slice it, it’s a favourable sign about increasing fitness, and as much as I dislike running, being more fit balances that out.
