I have to say the the combative tone of the article is highly off-putting, I think the author would reach more people with a calm, reasoned argument. I agree gatorade is not great for endurance sports, it's just too sweet, and there's not enough sodium.

Pedialyte is too expensive though, I use the Clif electrolyte replacement (lemonade flavor), it's got a ton of potassium and sodium and isn't so sickeningly sweet. It's also organic, and at $15 for a giant canister of powder is much more reasonable than some of the other powders out there.
