My wakeup heart rate was 57, so I went running. However, I was still tired and took several short rest breaks on the way back. Yesterday, I spent a good part of the day doing yard work, including mowing my lawns, and that caused my body to be tired today. Not only was there grass to be cut but lots of leaves to be sucked up by the mower. The leaves meant that I had to empty the bag more often, and a full bag weighed more. I have to do the Fall rototilling of my vegetable gardens tomorrow and/or Friday, so I'll probably be tired on Saturday.
Today was another great Fall day with temperatures in the mod 60s during my run. However, it will start to cool tomorrow and Saturday with snow likely in the higher elevations.
