Roxy and anyone else who just drinks "water",

It is vitally important that those of us who ride take sports drinks with us. Not only do they provide electrolytes but also energy that you need.

Not to promote this or that brand, I use Cytomax on all of my rides as it works for me. I have one bottle filled with water and Cytomax and another bottle with extra in it in a plastic bag. This way, when I get more water I add more stuff. I can also fill my 2nd bottle with water and sports drink if I don't have a place along the way where I can get water easily thereby having two bottles available. Since the Cytomax is in a plastic bag it is easy to transport via pocket or fanny pack (I use that a lot too).

If you drink your sports drink about every 15-20 minutes you should stay well hydrated. I don't drink alot, but I do follow this regimen pretty strictly especially when it is warm or when I'm doing a lot of hills. FOOD is essential as well. I take Lunabars and other stuff as needed depending on the length of my ride and available stores along the way.

There are also electrolyte tablets that you can buy-Endurolytes. They work well and are easy to carry with you.
