Well, My ride in the AM is only about 2 miles (10 miles round trip between two jobs all day) and the -2F temp with at least a 15 mph wind chill was less than pleasant. But I find that snow pants, balaclava's, and PI Lobster Gloves really help.

Although the doughy chunder snow really sucks when you are riding in the street to avoid the pedestrian-roughened sidewalks on busy streets...

Even the Marathon winters suck with chunder and pedestrian ice-paving-stones on non-road surfaces.
