It will annoy the bejesus out of your coworkers if you just keep sniffling every .5 seconds. At all costs, avoid this situation.

Wear something that covers your nose and mouth when you're on the bike and let the snot river do what it will. No one can see you, and it won't tickle once it's everywhere. It will just blend into the sweat and you won't notice it. Once the whole aparatus is saturated, it will even conveniently freeze solid in place!

Once you take the thing off and clean up as best you can, I suggest a combination of snot rockets and (gentle) glove-wiping.

BUT NOT EXCESSIVE SNIFFLING! Am I the only one who goes postal from this noise?
