For the water bottle

[margo49]

I read on a Thrifty Living type board that sports drinks are basically glucose or dextrose or fructose with a little salt. So recently I have been experimenting with that and have come up with the Ultimate.
Which is about 2 tablespoons of pomegranate concentrate ( A Turkish thing readily available here it is quite tart and refreshing), 1/3 tsp sea salt, and 4 level tea spoons of fructose. The last is sweeter than regular sugar so you don't need much. I make this up to 1 litre with water.
Might try the tea thing with a "bouquet" of home-grown fresh spearmint / lemon /verbena / melissa leaves. I drink that during the day at work. I make 1 liter on arrival and sit the jug (pitcher) to cool and keep cool on the air condition unit .Actually I am growing the spearmint outside the work window and am working on extending the "plantation" (just call me MacGyver)

the only thing that goes in my polar water bottles is water!

on century rides (or longer) i will save 1 or 2 propel bottles and fill them with garorade.... i keep those in my handlebar bag... and can throw it/them away when done!

for metrics and anything shorter i only ever drink water!

Yeah. Like Cali, I only have ever used water

But on a hot day I can see cold tea/flavoured water being a nice change

When my son and partner go out on Sundays for there 120km or more training rides they have water in one bottle and water with glucose in the other.
