So I walked and jogged again. It took me 1 hour to do 4 miles.

I did intervals of walking uphill/jogging/ and just regular walking.

I burned 550 calories.

So I feel like I am progressing. It may have been a very slow jog...more like a trot. lol But I was able to do it for periods of 5 min at a time and I felt like it was a good progression. I didn't plan on jogging, it was just easier than walking faster because my shins hurt when I try to walk really fast.
