I typically run alone, mostly because I'm about 6 miles away from the downtown area. But, when I was in Europe, I ran with a female friend. As I mentioned, it was great to have some company on runs and it really helped me to keep going out.
However, I've found some difficulty in running with someone of the opposite sex--the snot rocket. It's a well known phenomenon and we all do it without thinking when we're running alone. Heck, one guy even went through a "scientific" analysis. But it feels like bad form to me to do it when you're running with someone else.
Here's the obvious problem: you NEED to do it on a run--typically several times. I tried to sniffle a bit or I hung back a bit and waited for a loud truck to go by. So I was able to get by, but it wasn't easy.
I'm sure another guy wouldn't bat an eye and she probably would have been fine with it, but it just seems a bit uncouth. What do you think? When you're running and sweating, is this a very short step or is it still a big leap?
