The good news is you are young enough to get better rather quickly. You will need a road bike and that can simply be a N+1 deal anyway. Yes get with some local clubs and see how well you can learn pace line skills and pacing, climbing and sprinting. Then after about 5000 base miles see if you still want to Race. More good news is you can give it a shot at what are called public or open races. They don't require a license and are broken down simply by age brackets. There are also TTs in just about every area so you can check on those.
But you can always give it a shot and see what you like. There is a down side however. The 40 to 55 year old group is packed with Masters Ex pros and Cat 1 or Cat 2 riders.
