Wakeup HR down to 52

I had a nice surprise this morning -- my wakeup HR was 52. That indicates I had a good recovery from my run on Saturday in which I added 1.4 miles to the distance I ran the week before. It also indicates by body is starting to recover from the stress of my skin cancer operations (my wakeup HR has been 59-60 or more with an occasional drop to 56). If it is 56 or below in the morning, I'll run my 6.3 miles again.
