^^Yes snow multiplies the slowness effect by a million% Even today though riding on my slicks i was riding along at about 17-19mph, two months ago when morning temps where in the mid 50's i would be at 20-22mph, im not by any means a well educated person but, are we using more calories in the cold or something. I mean i understand the eyes thing in the cold i get the same thing, but im sure everyone here will probably say their times are slower in the cold there has to be a reason.
