You shouldn't sweat that much. Maybe lose one of the wool shirts and one of the longjohns? It is really hard to judge how many layers will be needed, but getting soaked is a bad idea.
And obviously, ideally your toes wouldn't be freezing. Bigger shoes with more insulation might help -- the trick is to insulate without cutting off circulation.
But I have to admit, I don't usually ride in such cold weather. I'm not opposed to it, you understand, we just don't get that much of it here in NJ.
Hmm....well im happy the longjohns....my legs were nice and warm...im just wondering about the shirts. I just feel one single shirt would be to cold. Dunno. Maybe I need two thing shirts instead of one thin and one thick. I guess I have to play with the adjusting.
I should I add, I commuted for about 8km. (6miles?)
