I can get the same thing sometimes so I blow alot of snot rockets. When I first start out, I'm blowing them every few minutes. But as I warm up and get riding, they get farther apart. After about an hour riding, my nose is all cleared out and dried out for the most part. It's worse for me to get a runny nose because I have a mustache and that stuff just gets all gunked up in it.
learn to do the snot rocket thing.
