Oh man, I had nothing alcoholic to drink last night, a super (read: healthy and not heavy) dinner and yet slept like dirt yet again. I blame stress.
The result was me not going to the gym in the morning but somehow I rallied in the afternoon and went at lunch.
So on the downside I was dragging all day but on the upside I ran for 20 minutes again and it felt fine! Unfortunately I wore some lousy socks for running and got a big blister on my left big toe but fortunately I didn't feel it until after I completed my run. I also ran slightly faster today than previously. Bonus.
Up, down, half full, half empty; it really is just perspective.
I went to FootWorks PT for another rehab session this morning and the diagnosis is that I am getting stronger and I got the official endorsement for slightly longer treadmill runs.
