I could tell as soon as I started running that my energy level was low. I should have aborted the run, but I continued on, hoping I would feel better after my body warmed up. I did feel better, but not enough to continue my run, and I aborted and returned to my car. My total distance for the run was 3.3 miles. Even though I had a good seven hours sleep last night, my wakeup heart rate was 59. This high heart rate was probably due to my mowing my lawns last evening. I usually mow the lawns on Thursday to avoid a conflict with my Saturday run, but, due to circumstances beyond my control, I mowed them Friday evening and only had a few hours for recovery before my Saturday run.
I didn't check the temperature during my run, but when I was in shade, the temperature felt fine. When I was in sun, the temperature was hot. Fortunately, due to the lateness of my run, there ware lots of shady spots on the trail. I went south from 100th South.
