I have been drinking a gallon to a gallon and a half of water per day. I work out 1-3 hours 5-6 days a week. in past months i could lose up to 5-6-7-even 8 lbs (upt to 4-5% of bosy weight)

In FL with the humidity and all for the last few months I have sweat majorly-- soakin wet type of sweating. Now, with is cooling off and the humidity dropping, I do not sweat nearly as much.

Should I keep drinking the same amount of water?
 
I would think that if your activity levels remain the same, your water intake should remain the same. If your body doesn't expel it through sweat though, you may find yourself taking more trips to the toilet than when it was more humid.

I'm in the middle of a UK winter and don't train quite as much as you do and I still drink about a gallon a day so, I can't imagine it will do you any harm.
 
work out 6 times a week, weights? jeez if i were you id cut that down a bit considering the amount of cycling and such you do.

Just drink as much water as you lose, your body should give you signs. In the summer and even now.

If you lose 2 litres (do the conversion yourself :p) and you consumer 2litres you have no net loss of water. But because you lose electrolytes through sweat and that, your sodium levels will be lower lowering your osmolarity of blood. This causes water in the blood to go to higher levels of osmalarity like your cells and interstitum which cause them to swell (lower performance!?) and increase the amount of water excreted through urine.

Thats why you see professionals in hot long duration events (or even normal conditions for that matter) have a sip of gatorade or something similar.
 
I think when he says he works out 6x a week he means cycling, running, swimming, etc.

But come now...he is Iron Man..you know hes gonna be working out to the extreme...:)
 
If you multiply your bodyweight in kg by 0.033 it gives you your water needs for homeostasis (approx) then add on 500 ml for every 60 minutes you exercise.

Its alot different in different weathers though but this is taken at an average not hot not cold temperature.

Sorry about the measurement system I dont do gallons and what not :cool:
 
Yeah so 2.3 litres per day then you add on 500 ml of water for every 1 hour of exercise.

Im not 100% sure on how reptuable this calculation is but it is interesting none the less

no not weights. Actually if I get weights in twice a week it's pretty good. I have endurance training plans. they are called bricks.

ie:
swim 60 min at RPE- 4-5
run 90 min (30 at RPE5-6, 60 at RPE 3-4)
Swim 30 min at RPE 5-6

cut it any way you want, it is 3 hours. See my log Matt- "performance is not enough" but go back a few pages,,, i just finished with a century bike race, and a 70.3 ironman, so i have been in recovery,....

i do take electrolytes a couple of days a week, pre- "long day" workouts. I also have nutrition and hydration plans in place for during exercise.

But- i have been dumping an additional Gallon or so in during my drive time, and at the office.
 
electolytes couple times a week? Try having some powerade during your exercise if its long duration and sweating a lot, youll probably see a difference..
 
Usual body water loss per day for normal activity is around 2500 mls. So, this is your base BEFORE exercise.

For exercise, weigh before you exercise and after. Consume that amount in water to make up for the loss. Consume 2 cups water for every pound that you lose.

This will give you a good base to go on. A great visual tool, despite sounding gross to some, is to monitor the color of your urine. If you are dehydrated or underhydrated your urine will be darker in color. If you notice this, drink, drink, drink. Good luck, Greg
 
well im not sure what the best drinks are, at least it has valuable sugar which would make any endurance trainer train or perform longer.
