I'm curious, what kind of speeds do you average in the winter? I understand the thickness of the snow definitely makes a difference, and ice will play a factor. Also, what are these speeds compared to what you do on the road when there isn't snow on the ground?

I average about 16 mi/h (25.7 km/h) when there's no snow, and I haven't ridden in the snow yet with a computer on my bike so I'm just waiting for the season to change.
