the best way to learn how to train for running is to start running... seriously. You dont need to bog yourself down and get all confused/turned around by what shorts to wear, which running goo is best, proper race day nutrition, tapering, Lactic Acid Thresholds and all that. YOu just need to start running... as soon as you build up your distance to a race-able length (a 5K or more).... even then, none of that matters. Not till you are preparing to be running for long distances does any of it REALLY matter. That said, anything by Hal Higdon is great. There is a book called the Complete book of Running for Women ( i think).
But again, youre getting ahead of yourself.
You havent even started yet, lol. ANd youre going to need to go slowly at first, due to your starting weight ( hard on your joints) No offense meant WHATSOEVER. Have you been fitted for proper shoes? I guess thats the only other thing that really matters...
What is your fitness level like right now? do you walk for exercise already?
