There is ONE loop I can do straight from my house that is relatively flat terrain. So that is what I did. The main loop is about a mile long, and By looping through downtown (also pretty flat) at the end, I ended up with 2 miles. I kept the run as slow and steady as I could. I didn't have trouble breathing, but I could feel that if I tried to go any faster, my lungs would protest. It will probably take them awhile to get up to speed. My legs on the other hand, were ready to race and begging for speed. As for my foot...I think it was ok? I think there was a tiny bit of an ache during parts of the run, but I was so focused on looking for it, i'm hoping I just imagined it. I iced it afterwards just in case. And stretched it. And rolled it on a hot water bottle later in the day.
Oh, and I ran that 2 miles in 15 minutes. So relieved I can still jog below an 8 minute/mile pace!
I'm still not sure exactly how I'm going to go about this return to running...but I think I'm going to try to start by doing that 2 mile loop every other day and see what happens.
