My wife wasn't feeling well this morning, so I went running by myself. It was a nice morning for running, temperature being in the mid 60s (F). However, in the afternoon it clouded over, and forecasts were for rain.
I felt fine during the first half of my run and didn't take any rest stops. On the way back, though, I took three rest stops for about a minute each. I felt stronger during my run, and I think I'm slowly getting used to this distance.
