The temperature broke and we had a morning with low humidity and cool weather (for summer in the south) so I had a great run. I was faster than normal by 1 1/2 minutes per mile and it didn't feel like I was pushing it that hard. I love that kind of run. The bad news is, when I was running on a sidewalk by a busy road, a dog started barking at me from across the road and actually ran at me. It turns out that he was very friendly and had a collar on and just wanted to say hi. I petted him and continued on with my run. As he went back home, he got hit by a truck and died. That just wrecked my day. Has anything like this happened to anyone else?
