What LPH said.
Learn to blow "snot rockets". Yes, it's rather un-ladylike, but its much easier on the skin around your nose than constantly wiping it on the back of your gloves. Just watch out for riding buddies, pedestrians, cars, etc!
(I just had this conversation while hiking with some of my aunts yesterdayOne thought snot rockets were disgusting, while the other two thought it was perfectly acceptable. Not suprisingly, those two were the more athletic of the three of them.)
