So, you wanna be a bike racer?
You won't regret it. Fantastic people to hang out with, but it's really hard. It hurts, a lot. At some point in nearly every race there's a split moment where I think, "this is ridiculous," and then it's gone, replaced by the thrill, pain, resolve or whatever else is required to survive the engagement intact and on target for what I wanted to get out of it.
You'll get to know yourself -- your strengths, definitely, but perhaps weaknesses even more so, and you'll either quit, or begin to address them and become a better person for having done so. In my own case, facing up to a streak of quitter if the going got too tough was no picnic, but racing provided the means to address it, kind of like having the right tools to control bind weed.
Discipline, determination, commitment and optimism are must-haves, or must-develop, characteristics if you're going to do this thing. Even the most fun-loving, beer-quaffing, I-just-do-it-for-funners consistently put in hundreds of hours each year on their bikes.
All that being said, if you're still interested, I'd be delighted to show you the ropes and help you get started.
