This is one of those things that only the experience of getting out there and doing it can answer your question. In my mind it doesn't matter if you end up loving it or hating it. The important thing is you're going to try it. I've tried racing, and like BD, it's not my cup of tea. My competitive juices tend to flow stronger in other areas. And it wasn't the discipline or the pain that came with training that turned me off. Rather, it was not appreciating the experience of racing past many sights, sound, and smells that come with bike riding. (As an example, if you want to see my pace/speed drop, follow me when I'm riding past wild roses, lilacs, or honeysuckle. I slow down and breathe deeply to experience as much of those smells as possible. Those wonderful scents let me know that life is good.) You, however, may find that racing is a really good match for who you are or want to be on the bike. Go for it.
