Restricted Sprint?

I think the adrenaline you get when you're running away from a monster is high enough to keep you sprinting for hours

Yeah, but they should do some kind of sprintcap so that when you're in a calm area, maybe solving a puzzle you won't be able to sprint forever. Imo there shouldn't be any bar that shows how much stamina you've got left, but if they'd do so they should make something similar to the sanity- and healthbar, but instead of a heart or a brain it's a lung
