I've been commuting by bike, and have a mountain bike that I ride on gravel roads and state parks, but I ride for recreation. I recently saw that the Missouri Show Me games has a 50-59 female category for their 20 mile cycling race. Gee, I'd like to do this, and boy I'd LOVE to win. Last year's winner did the 20 miles in 56 minutes. I currently have a Trek 7.2 fx, flat bars, can I do this race on this bike, (of course I would put slick tires on it) or do I need to go ahead and get my dream Bianchi Eros Donna? Or am I over-thinking a 20 mile race? Anything you can recommend to train for this? Suggestions, books, whatever? I have until July 22nd, so anything you guys tell me, I'll try. I've been dancing/teaching dance since I was 8, but I've never really competed in anything. Boy am I looking forward to this!
