So far, I've ridden more this January than any other I can remember, starting with ~15mi on 1/2 when the high temperature was 18F and a 20mph wind. It warmed up unseasonably shortly after that and I was able to get multiple rides in, culminating with ~40mi last Wednesday when the temperature reached almost 50F. Since then it has snowed several times and there's still enough snow and ice on the roads to make riding unpleasant.
