Well, I usually don't ride when the temp is below 0F, and last night the weather report said that our min was going to be 10F, so this morning I hopped on the bike and set off on my 15 mile ride into work. A mile into the ride I look at my thermometer, and it is reading -2, as I continue my ride, the temp dropped to -10. Got into work with numb toes and fingers - reminded me of why I don't ride at below 0!
Thank goodness for the slush that makes the pedalling harder - keeps me warmer!
