I haven't been able to run for a few days, since DS had snow days the last 2. Today he was back in school and I wanted to get in 4-5, but it was in the teens with 2ºF windchill and my asthmatic lungs weren't having it. So I did 3.3 and called it a day. I did use the last couple of days to put some miles on my bike on the trainer, so it wasn't a complete loss.
