Since you are posting here, the question you are really asking is, "How do I become a self-coached athlete?" You start by informing yourself.

Friel's The Cyclist's Training Bible and Cycling Past 50 are standard texts. Brzycki's A Practical Approach to Strength Training is also good. Sally Edwards has a number of books on training with a heart rate monitor: http://thesallyedwardscompany.com/sa...ly-edwards.php
Google "athlete nutrition" for a gaggle of articles and books about that subject.
Hammer Nutrition has a PDF book that coves many aspects of nutrition, hydration, and electrolytes:

Then the next thing to do is to ride your bike, and ride it more. As you start riding and training, you'll encounter problems and have to figure out the solutions. That's the hard part about being self-coached: you only have the one data point. As you go on, you'll accumulate data points and start to have some idea about what works for you and what doesn't.

This forum primarily deals with helping athletes resolve problems, rather than giving general advice which may not be right for you, or even make much sense.
