My friends and i have found this incredible electrolyte replacement drink - Elete. if you have not heard of get it in a bottle and only need to use a few drops for a 8 oz. of water. the cool part is that it is add it to water and it still tastes the same. you can add it to your camelbak too. we used it on a 24 hour race and didn't have any problems! no cramping, no dehydration, etc. i would highly recommend it.
