Thermometer read 9 degrees before I head out the door. This was at 8am, so I guess it had warmed up. It was chilly, but if you dress properly, you get used to it. Like running in extreme heat though, extreme cold can zap a bit of your energy, or just make you feel like you're working harder than your results reflect. I ran from home, through the U, to Foothill, then zigzagged down through the Harvard/Yale neighborhoods to 9th and 9th, then continued to Liberty Park for a couple of laps, and then 6th East through downtown, up Canyon Road toward Memory Grove, and then east on 4th Ave. to home. My left foot didn't bother me at all until the last mile when I started to feel it. I iced when I got home. It's manageable, but I should probably have it checked out to be on the safe side.
