So it's humid and gross in Houston and that means my face is dripping sweat in the first five minutes of a run. I use a head band and that helps a little, but I still end up with sweat mixing with my sunscreen and getting in my eyes which is not fun. I hate carrying anything in my hands while I run, so I don't carry a towel. I try just wiping it off with my hands, but my hands also get sweaty, so it doesn't do much good. Suggestions?
