Carrying Your Own Drinks
Have you ever seen a runner win a marathon with a drink belt around his or her waist or a fluid bladder on his or her back? No, and you never will, because it’s a terrible idea. Fluid weighs a lot, and extra weight slows a runner down dramatically. Every running event worth participating in provides adequate drinks at aid stations. Use them. Even if the sports drink offered is not your favorite, you will almost certainly perform better by drinking it than you will by schlepping your own preferred beverage.
