I mean sure, that's sort of a given. Are you suggesting you don't piss?
Maybe you just hike differently to what I assumed.
I do the occasional hike anywhere from 4-8 miles and I usually drink an extra 1-2L for the day - that's how I reckon I'd double my intake for a 12-15 mile hike.
I don't piss like a race horse, the hikes are in 95-105 degree weather, and I go at pace. To each their own.
