There is some serious discussion here about what racing is like. Don't let this dissuade you! Stick your toe in the pool and give it a go. Don't be worried that you'll be sitting off the back after one lap wondering what just hit you, that's just the way it is for a new racer, no matter the fitness or skill level. Racing is NOT like a group ride, not one iota, but still - it's a blast! If you decide you want to pursue racing, in order to stay in the pack and have some fun, you'll NEED to TRAIN. That can be consuming, time wise and mentally, but if you're serious about racing, it's a must. I've gone from blasted off the back in every race to mid-pack/near the front in one season. Now it's REALLY fun.
