OK can you all tell I'm excited - sorry to keep bombarding you with questions!

I've been reading about race etiquette and it all seems pretty common sense, but one thing I haven't seen mentioned is audible alerts. I have a hard time judging my pace and it would be really helpful to me to set my watch for audible alerts. I've found that when I look at my wrist, I pull my head and shoulders back to do it and it automatically slows me way down. Is it rude to have beeping going on and annoying other runners? (I figure it's probably newbie behavior and not at all comme il faut, but is it rude?)
