I drink more during bike rides than anyone else I know. For example, during a recent group ride, most riders had two bottles and didn't finish them before the rest stop. I had five bottles, and drank them dry before the rest stop. I recently bought a Camelbak so that I don't have to carry so many bottles, which takes care of the immediate problem.
I drink mostly h2o, and sometimes diluted Gatorade or Cytomax. On long or hot rides, I make sure to get plenty of electrolytes, either through food or pills. So long as I drink enough, I feel fine. If I try to cut back on fluids, I fade very quickly. I guess it may be psychological, but I don't think so.
It probably bears mentioning that I sweat copiously, too. And when I say copiously, I mean copiously.
Does anyone else have this issue? Is there a better way to approach it? Should I be worried about anything?
In general it isn't a great idea to over-hydrate. But if you are drinking because you are thirsty (rather than to some pre-set timetable because you think you're going to need it) and exhibit none of the symptoms of hyponatremia, I guess you're OK.
