Now, on a day hike of 6-8 hours, I have never carried 3-4L even on warm days. Does anyone carry that much? Pretty serious weight for a daypack.

It's long suggested that people should drink around 500ml/hr when exercising above moderate level of intensity. Coming to bushwalking, similar volume has been recommended too. Now, on a day hike of 6-8 hours, I have never carried 3-4L even on warm days. Does anyone carry that much? Pretty serious weight for a daypack.

For a 6-8hr hike, I would carry 1L in winter, 2L on an average Sydney summer day, and 3L during a hot spell. I've never carried more, except for a dry camp.

Once you are on double or triple portions, it's hard to go back to single.
I understand more people have died in marathons from hyponatremia than via dehydration.

Unfortunately this logic does not follow based on physiological foundation.
The key difference here is that the body can store more and more digested excess food calories in the form of fat (hence the bigger and bigger beer belly) through the various metabolic pathways for longer term storage, the body has no longer term storage mechanism for water. Water gets absorbed and excess is excreted quickly, carrying salt with it. As such, our water consumption can only be within the envelope of our physiological capacity to handle it (both low and high ends) or face potentially deadly consequences.
