I ran 3.9 miles outside this morning. It was 28F when I started, and had dropped to 24F by the time I got home. Everything was warm enough after I got moving, except for the toes and chin. Why my chin and not my nose, I have no idea... Did have some excitement, though: I was chased by a Great Dane that probably outweighed me. He just kinda stepped over his fence and came galloping down the sidewalk towards me. I stopped, and he just wanted to be petted. Still, that'll wake you up in the early a.m.!
