Still Tired today

My wakeup HR was 53 again. I still felt tired, so I ran the 5.9 miles again. I'm going to be taking off next week due to skin cancer surgeries, so I wanted to get a few miles in. After I recover from the surgery, I'll have to work up to the 6.4 miles that I've been running and then do smaller increments to get back up to the 7.8 miles.
