I realize that it's a bit late, but you can sum up most of the stereotypes by watching College Humor's video on bronies. I know the video was a joke, but it is mainly what inspired me to start running, and lose 30lb's. Now, I couldn't be more happy that I haven't been contributing to that stereotype. We are a group that people feel the most comfortable pre-judging. Use this fact to your advantage. Spread the love, crush the stereotypes, and be healthy. Judge a book by it's pages, not it's cover.
