I am a (newish) runner looking to get into cycling seriously. I have done quite a bit of spinning and I love it but no real outdoor cycling. I'm trying to decide what type of bike would be best for me. I don't want to get anything too expensive right now since I am only testing the waters but I do want something that will be efficient. I don't know whether to get a road bike or a hybrid. I know I do not need need a mountain bike so that's not even an option. I live in South Florida and will be doing most of my riding on the road but I do want something that is comfortable enough that I will actually get out there and cycle. Right now I'm more concerned with actually getting into the habit of cycling and not so much with race performance so I need to keep that in mind when choosing a bike. However, if all goes well, I'd love to do a duathlon and maybe even a half century late next year.
I'm also just under 5'2" so size is also an issue. Any thoughts? I know that you guys aren't psychic but maybe you can help throw some light into the road vs hybrid issue?
