Interesting. There was an article someone posted here a while ago that suggested that women don't store carbs (glycogen) the same way that men do. And, since we can't carbo load as effectively, we need to make sure we consume carbs along the way. My BF can ride for hours with just water (and he's quite skinny) and I need carbs in my liquids almost immediately. That study kind of agrees with this one that we need that breakfast boost right before the workout because we can't store it the same way.
