Tang as Sports Drink? uvagradk 1/7/04 10:27:25 AM ET
I'm preparing for my second marathon in March. Until last week, I've used a 1:1 mixture of powerade and water as my sports drink. On long runs, I also use GU gels. On a whim, I bought Tang at the grocery store and was suprised that it offered more carbohydrate / serving than powerade (19g vs. 23g.) The cost of the two drinks is almost identical. There are two differences that I'm interested in: salt and potassium. Tang has about 1/2 sodium of Powerade and Tang has no potassium (Powerade has about 1% of RDA potassium). On long runs, I'll get potassium and salts from GU gels and the potassium in Powerade doesn't appear to be significant. In general, it's a good idea for me to limit my sodium as I have been told to do so to prevent a reoccurence of kidney stones. But I can certainly limit sodium in the rest of my diet. Any thoughts on electrolyte balance or other issues? Thanks.
