We recommend that you drink at least 8 cups of water a day

1 cup is usually 8 ounces, about 225ml?

Ah ... thank you! So about 2 litres. Thanks

Anyone know how much they compensate their exercise with? Do you drink an extra litre?

I've actually done testing on water intake. My indicator being urine color. I've found that 1/2 my weight in ounces is perfect and I've never gone "yellow". I also tried 32ounces less and still no change. Finally, another 32ounces down (or 1/4 my weight) and BAM, dark urine. I work out for 1 hour per day, 7 days.. Hope this helps you.

I weigh before and after a run and drink the difference, on top of my other water intake for the day.

Great reply, thanks. I drink during my work out ... though.

Still do it, see if there's a different from start to end even though you are drinking. This is what we all used to do while I was a competitive swimmer and sometimes with a hard two hour session even though I was drinking water throughout (and utterly sick of water by the end) there was still a loss that had to be compensated for.

8 ounces = 1 cup. The rule of thumb though is really 1/2 your weight in ounces.

Thanks, I cant get my head around ounces... for liquid strange to me, i only deal in ounces weighing ingredients when baking cakes :-) Fluid ounces?

My weight is 326 pounds, so that's 163 (fluid) ounces = 5 litres. That right?

No basis in science for drinking that volume of water (in fact there's no scientific basis for 8 cups / 2 litres per day either.....it's just easy to remember).............5 litres of water a day is probably excessive and at the very least you'll spend the whole day in the bathroom. There's also a slight risk that you can upset your electrolyte balance (google hyponatremia).

Don't forget that there's water in everything you eat which forms part of your fluid intake. Drink regularly throughout the day, you can judge your state of hydration by the colour of your urine (should be light, not necessarily clear) and by pinching the skin on the back of your hand to see how quickly is snaps back (less reliable as we age and lose collagen)
