My wakeup heart rate this morning was 61 and I felt tired. I did run/walk, but I reduced the distance to 3.5 miles instead of the 7 miles that I'd hoped to run. I did, though, increase the number of left-foot-steps of running from 102 to 103, keeping my walking at 66 lfs. About half way through the run I could tell I was getting tired, and I reduced my running and walking to 66 and 46-50, respectively.
The sky was overcast and the temperature was in the mid 30s (F). Not a bad day for running, but it was cold for an old guy like me who was tired. The good news was that the path was free of ice.
At noon I had a check-up on my surgery (last week) for a Basal Cell skin cancer (the skin graft is doing fine), and I went running in the mid afternoon.
