I hate running/playing sports against men. They do the DUMBEST stuff to just avoid getting beaten by a woman. They will block you (both individually and in teams),run over you, trip you, whatever it takes to keep their precious egos intact. Then at the end of the day, you still beat them, but it's annoying to have to deal with fragile male egos for something that is supposed to be fun. I stopped playing co-ed sports when I got literally run over by some dude who just didn't want to accept I was going to beat him to the score. It's not fun to get run over by someone who outweighs you by 60 lbs.  Another time I ended up with a bone bruise from a guy who kicked me in the shin so I wouldn't beat him. And it's definitely not fair or sporting to have to try to compete when there are a bunch of guys purposefully working together to block you from passing them.
