I wish I knew it was like crack...only more expensive. Welcome to the TerrorDome!
Seriously--you're going to LOVE it. I went to
www.beginnertriathlete.com and got advice, information, background, experience and trainning plans. It's all good.
You're on the right track--Don't ramp up too quickly. Most people say 10% per week increases--maximum.
Also,
www.active.com allows you to look up events by state. It's a good place to start looking. Start with a Sprint or Olympic distance (not that much more) to get your feet wet and get some experience.
Dude...you are sooooooooo going to love this!
