Does Goo Really Work to Help You on Your Runs?

"So does the Goo really work? It probably does after the race. Carbohydrate loading and drinking plenty of water are adequate enough to keep you going during the marathon." This article, says that there is little benefit due to the amount of time required to get the carbs nito your system. Some benefit? Yes. However, the suggestion is that there is more to better hydration than consuming goo.

Is this blog starting to sound convoluted? Drink lots of water, don't drink too much, calculate your need, don't worry about it. and then get 8oz. every mile. It is enough to get me confused.
