Snot Rockets.
I’ll go ahead and put it out there: if you think snot rockets are gross, you aren’t a real runner.
This is a very relevant topic when training for a marathon in the winter. Especially during long runs. The ability to properly execute a snot rocket is a coveted skill in the running world. I’ve got it down pretty well. But I’m definitely still impressed on windy days when I see another runner turn her head and clear a nostril while totally avoiding her shoulder, without even missing a stride. It’s a skill to be perfected. So, when I get a grossed-out look from a well-dressed man in a peacoat, I remind myself, “he’s not a runner. I’d like to see him blow a snot rocket like I can”.
