I don't think that is at all unusual--I learned on winter hikes that it is really helpful to have a spare bandana as a "snot rag" (yes, that's what somebody in my group called it, and she recommended tying it to your backpack strap so it's easily accessible). I think everyone's nose runs when it's cold.
