Well for some of us the weather is quickly starting to drop and in no time the ugly white stuff will be dropping from the sky. Right now in my region (Massachusetts) we are getting weeks with highs in the 50's and lower lately. I'm not much of an outdoor rider once snow flies anymore because of my asthma and cold temps so indoor training rides with some treadmill work start once the white stuff falls. I might manage a couple rides outside in January and February if a little window opens for it.
So where is your outdoor riding limit, or do you still ride outdoor all year long no matter the temps and conditions.
