Title: Not what you need for Marathon training.
Review: I cannot believe that this product is used in the LA Marathon course. This drink only have 15 cal per serving with 3 g of carbohydrate. More importantly the electrolyte content is very small. The potassium level is only 75 mg, calcium level is only 25 mg, Magnesium level is only 8 mg and the sodium level (what you need the most) is only 5 mg! If you're endurance athlete this is not the drink for you. The only way to incorporate this drink, if you carry additional source of calories and/or electrolytes. This is possibly more suitable for athletes doing a mid week, one hour work out and trying to lose weight. Is my opinion that one can make a better homemade sports drink. One recipe on runnersworld.com, Has 12 ounce of water, pinch of sea salt, a quarter wedge of lemon, and tablespoon of honey.
