This morning was -13F; took the 10 mile route. I'm happy there was no real wind this morning. And even happier that this the last sub-zero day in the forecast!

This is roughly the lowest temp I've ever biked in; last January was maybe a couple degrees colder. I wish my Garmin was more accurate, the 510 is not well calibrated for sub-zero temps. Today the Garmin was reading -22F when NOAA is reporting -13F.
