Making isotonic sports drinks?

[Ball123]

Anyone have a good recipe for making isotonic sports drinks? They become quite expensive to buy in the long run.

The recipe I use, which is recommended by the WHO and many other organizations is as follows:
6 tsp white sugar, 1/2 tsp table salt, 1/2 tsp salt substitute (for the potassium it contains), 1/2 tsp baking soda and 1 litre of water.
It tastes better if you add some lemon juice to it. If the taste is too strong, which sometimes it is for me, I just dilute it. Either way, I'm getting fluids and electrolytes, it just takes a little longer to feel better if I dilute it. I also take a calcium/magnesium supplement.

Actually, I do not. However, I just noticed in this months issue of runners world some great low fat recipes that are unusually high in carbs. For example, on page 48, they list the breakfast of champions, 1 cup oatmeal topped with 1 Tbsp honey, 2 Tbsp dried cherries, 2 Tbsp walnut haves, 8 oz of plain kefir, and 1 medium banana. This supplies 600 calories and 90G of carbohydrate. No bad for breakfast. (But watch your calories if you aren't burning that many).
