So, today is my first day back in my running shoes, and it turns out, they're right! I've clearly lost ground, but that's to be expected, and my stopwatch died 8 minutes into my run, so all I can say for sure is that I ran 5 minutes and walked three. After that, I'm guestimating I did intervals of 7 running, 3 walking and 6 running, but who knows? The point, though, is that I can still run, I feel great, and my knees don't hurt at all. Yay!
I have exercises for my knees, which I'm doing slightly less frequently than would be ideal, but still within the range of what the PT said I should aim for, but even with only about 3 weeks of that, I can feel improvement, which probably also relates to not running for that time, too.
Anyway, I'm feeling good, and I'm glad that I didn't entirely forget how to run in my time off. It's silly, but I really was kind of worried about that.
Also, I got to try out my new summer running attire: a running skirt! It's awesome. I'm ordering more as soon as I click "post".
