In the January edition of Beginners Beat, we learned that water - in excessive amounts - can be hazardous to our health. What's next? Breathing is bad for us?

Actually, in some cities in this country it can be, but that's for another story.

If over-hydrating on water is an increasing problem among runners, what about the consumption of sports beverages?

"Sports drinks can be a problem, too," said Dr. John Cianca, medical director of the hp houston marathon. "While these beverages contain sodium, they are still relatively diluted. You're better off snacking on some salty foods before and after a run than relying on sports drinks."

Pretzels, peanuts and the like are good options. Dr. Cianca said since most runners don't have blood pressure concerns, consuming these foods is typically not a problem.
