My wife and I were out about 10 am. The temperature was in the mid 50s (F) when we started and in the low 60s when we finished. Quite a few people were on the path. We went south from 100th South. That route doesn't have much shade, and we took advantage of the warmth from sun. I took no rest breaks on the way out, but I took three breaks on the way back, at the 1.3, 1.8, and 2.1 markers. I'm always more tired on the way back than on the way out.
I am getting stronger. Today I went 1.3 miles before I took a break. A few months ago, I was only going about 0.75 miles before my first break. I am trying to get more sleep, but I'm still only getting about 6.5 hours of sleep each night.
