So, I did it. I ran the full 20 min. Not really that long, but I reached that barrier that I had been struggling to cross. It felt good. I ran my usual route backwards, but little did I realize how much of it was going to be uphill. It was a push to do it, but I felt better for having done it.
I was passed by another man running this morning, and it reminded me of the time when I could like he did. Uninhibited by my added weight and lack there of physical fitness. I wish I could get to that point again, but it will take some serious work to do it. I guess I have to convince myself that I am up to the challenge.
