The even better news is that Zico seemed to work very well for me. I brought my sloshy fuel belt (which I hate because it always makes me feel like I'm rockin' the 80s belted-shirt fashion)
But I'll sacrifice style for hydration any day.
Zico's got a very mild taste. It's nothing like the "coconut" flavor you'll find in a Mounds bar or anything. It's cultivated from young coconuts and is clear (hence: coconut water) instead of milky. If you wanna learn all about it's nutritional info, feel free to click on the link.
I'd had coconut water a couple times in India. Street vendors sell fresh coconut for a couple rupees and they look like this:
My friend, Rajiv, sucking a coconut
On my run, I drank about 4 ounces every 3 miles. I guess the downside of training with coconut water is that it's unlikely to be the beverage served at aid stations in Austin. I don't think I wanna be the "80s Marathon Runner", so I'll have to figure this out as the race draws nearer.
