I hydrate properly in winter and summer. I just think some people happen to drink too much on some rides and some probably need a bit more than otherssampras38 wrote:oldwelshman wrote:
I am managing on one currently in this weather and sometimes even have some left in the bottle. If it does get a bot warmer or we ride a bit harder I just top it up in the cafe stop.sampras38 wrote:NapoleonD wrote:stokepa31 wrote:about three hours. i like to stay well hydrated
Blimey!!
That you do!
In the current climate I'll take out two 750ml bottles, one with energy drink, the other with squash, and that does me bob on for 5 hours!
Nap, how hard are you riding on those 5 hours as 2 bottles doesn't seem quite enough to me. If you can do it, then more power to you, but that's really not a lot of fluid in 5 hours. Do you have much fluid before leaving the house?
When you get back after the ride, how soon do you need to pee? A good indication is if you pee after the first say, 20 mins, you''re probably hydrated enough, but if it's much longer you're most likely de-hydrated.
And apologies if I sound like I'm preaching...;-)
From about may on, I use different bike with two 500ml bottles.
You do realise that you lose fluids through your breathing too, so it's just as important to hydrate properly in the winter?0 -

0.8L - 1.3L per hour depending on the drink, 1.3 being a "proper" sports drink and 0.8 being pure H20.
You lose 1.5L - 3L an hour though. :!:
If this is the case then how come I do not weigh 7.5kg lighter after a 5 hour ride?
Or is sweat lighter than water? 0 -

do you not eat?
how do expect to sweat out 7.5kg if you only drink 1 bottle? its all relative.0 -

please define this 'performance'.
power output?
efficiency?
energy levels?0 -

I was merely responding to Bhima's sweeping statement that you loose 1.5l to 3l per hour, in which if true, I would expect my weight to be minimum 7.5kg less after 5 hours?
It is of course dependent on the intensity of the ride and the temperature.0 -
thirst is no use. its very poor. you can become seriously dehydrated and not be too thirsty, as pokerface found out.jibberjim wrote:ride_whenever wrote:The only surefire way to monitor hydration is by naked weighing of yourself.
How do you account for the calories you burnt, both fat and glycogen, and the associated reduce water needs because of the water that was released from its associated storage with the glycogen?
Even with "naked weighing" surely you'd also need to know not only the calories expended, but the mix in terms of fat and glycogen that it came from.
Of course even if you absolutely fully deplete your glycogen stores, you're only talking about maybe 750g at most for an average man, but that's still a large discrepency in terms of water lost.
Drinking to thirst is probably better for all but a small minority of people.0
