I don't think it was a matter of number of men, rather it was the event was geared towards women. Men weren't (still aren't?) able to start in the first corral, and for the first year or two, they didn't even offer shirts in men's cuts. But for whatever reason, they did do awards for the 10k, just not the full.
But yeah, I had the same idea, just missed 3rd in the 10k a few years ago. Go for it, good luck!
Yeah, go for it @RunningKoen! We expect you to be in a tutu, though....
