Another 4 miles
Except for the heat, my run was uneventful. The shade temperature was 80 (F) when I left home and 89 (F) when I returned. Most of my run was in the open sun, and the effective temperature in terms of heat transfer was probably over 100 (F). I didn't have any water with me, and I felt the sun. I took a lot of brief walking breaks. On the positive side, my wakeup heart rate was 51. It has been in the mid 50s for the past few weeks.
