Morning run and what the ???'s up with my heart rate?

I don't know... I just can't get pictures uploaded anymore. I'll have to problem-solve that when I have more time.

Anyway, I had a pretty good run today. 3/4 of a mile without stopping? Been there, done that - for the first time today, at least. But I did it twice, for what that's worth. (Last time doing the program, I stopped shortly after completing 1/2 mile without stopping.) Though I should be intimidated about Friday's run with 2 miles without stopping, but I actually am looking forward to it. The only thing that will prevent me from running Friday is my left knee. It's starting to have some tinges of pain, but it hurts more when walking than when running. I'm icing it now as a precaution and if it's not better by Friday I think I'll have to give running a break.

My heart rate was really weird today. You'd know what I mean if you could see the graph... Oh, how nice it would be to be able to upload pictures... Anyway, it's a nice smooth line wavering between 160-170 while running, but when I did the walking portion, it fluctuated wildly between 134 and 220?!? I'd think it just shifted out of place, but it smooths out again during my second running portion. What the hey? Really weird.

Today's run: 2.65 miles in 37:22. Overall pace: 14:06/mi. Flat course.
