I ran 6 miles again this morning. I still walked a bit, but not as much as on Saturday. My wakeup HR was down to 52. The lower HR and the reduced walking indicate that my strength is returning. Over the years, I've observed that when I'm out of running for a period of time, it takes me about the same time to build back up as I was off. From that viewpoint, by the end of next week I should be back to my pre-surgery running level.
It was a nice day to be out. Comfortable temperature in the 50s, beautiful clouds. It's great to be alive!
