I am orginally a runner but in the past few months I have learned of a knee injury that will keep my out of running for the rest of my life. I used to bike alot when i was younger and my bike is now rusted and in the shed. In the very near future I have been thinking about buying a bike, what kind I don't know. I was thinking something in the road cycling area, in the NH area there are many bike races that interest me alot and I would very much like to get involved in. As a new biker what should I really know? Right now my price range is at about $1,200-$1,500 and I would like to get a sturdy bike that I can ride and possibly race with. Just eating habits training methods and just what would be a good bike that I could get around with and stay in shape. Thanks for your help.
