Did someone put weights in my shoes?

On the first of my shortest run in ages, I was thrilled to have only 3 miles. That meant I would be out and back before I knew it. There was only one thing stopping me, the weights that someone put in my shoes. Oh, I wish I had that excuse. I ran at almost the pace that I plan to run for the marathon, which is slow in my books for the distance I went. Maybe my body is just preparing itself for that pace? Highly unlikely, but I'll test it out again on Wednesday. Hopefully it was just an off day.
