My original plan was to do an olympic distance tri in september just for motivation to build some fitness. My reason for posting on this board is because as I have been riding (along with some running and swimming), I am thinking about shifting my focus to the bike (using swim and run as cross training).

I would love to get in some really good cycling shape, but need a rough guide to get there. Thanks for your time.

*I just purchased Thomas Chapple's Base Building for Cyclists. It may actually be more technical than what I am looking for, but it seems like a potentially valuable resource.
