Temp was 13°F leaving this morning with a 25 mph wind (gusts of 35) pushing me all the way to the office. I'm not sure I'm ridden that fast on a 4.5 mile stretch with the fat tire bike before.

The windchill was -3° but didn't even feel it with it pushing from behind - fun ride.
I'll be riding directly into the wind on the way home, so I'll be getting my workout in today.
