so cold my bike did not want to move at all, think it was protesting. Might need to lube my chain and clean up a bit. Think it was frozen, poor bike. I was warm enough as I was layered up for skiing this afternoon, but I was way out of breath today. But we are supposed to heat up to low 50s by the end of the week, it was 8 this morning but everyone said more like 5. Whatever it was I had to wear a jacket when I ran this morning.
