On Sunday and Monday my wakeup HR was up at 53. Today it came down to 50, and I did a 2 1/2 mile "light" run. I felt tired during the last half of the run and did some walking. I've had pretty good sleep since I added 25% on Saturday, so I think the increase in HR was due to adding too much distance. Thursday is my next day for running, so I'll see how I feel then.
