Run in the morning, starting out a little before 6:00 and hoping it would lighten up during the run. Standard loop through the neighborhood. It didn't, much. At the end, it was still dark enough for me to have to watch where I put my feet down. My running fitness is coming back little by little. I was able to increase my pace generally throughout the run, which was a change from recent efforts. I think my GPS didn't recognize the location until after I started, which probably explains the slightly lower distance recorded.
