I DID IT! I did it, I did it, I did it, I did it!
It wasn't quite the traditional way; I ended up having to stop with 3 runs to go to talk to a neighbor (this is why I don't like to run on my street) but it actually worked out well. I was about to give up, because my ankle was screaming, but while I talked to her (for about ten minutes) I stretched and ran in place... the ankle stopped hurting, and I finished my last three runs!
I exercised for 45 minutes total (including the neighbor chat) and ran/walked for 1.9 miles! (That's according to my pedometer, the accuracy of which I doubt.
I drank plenty of water, and stretched afterwards after my cooldown walk, in the house.
I feel fantastic. I grinned like a total moron during my last run.
It was SO much easier. After two runs the first day, I was already panting and breathing so heavily, but this time, I hit run three, and again with the idiot grinning.
I feel so proud of myself. I can do this (and kept telling myself that during my runs. I had to coax myself to do this, a lot.)
