:(
But bad pacing. Also a couple days of insomnia on Friday and Saturday night that I'm still feeling from some heavy upper body lifting related to yard work. Either have to lift heavy every day, or when I occasionally have to I get insomnia. I'm guessing the increased blood pressure causes issues perhaps with my bicuspid aortic valve. Not an issue with legs because they're getting plenty of increased blood pressure daily from at least walking...??

Then half miles: 1:51, 1:58. Very tired today.

Still an improvement of a second, and the pacing was really bad. And I had insomnia. And I had to go five days between because of work.
