Thanks for all the advice! I bought the bike from a bike enthusiast who lives in town here, so he had cleaned and tuned it up pretty nicely. I have no complaints with it at all, except for the vast number of people who FLEW by me during the tri - lol! SO, I think I'll take the majority of advice and just invest in a road bike, but keep my "Ol' Blue" and keep training on her to build up my leg muscles! Plus my butt finally got used to the seat, lol

I'll try and post a pic later. Thanks again everyone!
