It's been really hot and I've been back on the Gatorade for cycling and golf. Everybody always says they cut their sports drinks with water, sometimes for cramping, sometimes for taste, sometimes just because .... people do it. It becomes automatic. Well, Gatorade, which is what I use and like on rides of 2-3 hours -- it works well for me -- is already diluted. It's mostly water. Way mostly water. I drink plain water, too, on my rides, but the Gatorade I drink straight. When I mix it with powder, which I often do, I mix it full strength and then get it real cold. I trust that the labs that came up with it back in the 60s figured out the ratio of water to salt/sugar/electrolytes. Notice the labels don't say, add water, or dilute.
By the way, I think the stuff tastes just awful unless it's really, really hot out and you're sweaty and you're drinking a lot of fluids.
I just wonder when I see so many cyclists drinking lots of water AND their sports drink is half diluted, are they getting the benefits? Maybe it's just a matter of taste.
