I use Endurolytes this way: I don't take them at any particular rate. I drink to thirst. I know about how much water I need to drink at a particular effort and temperature. About X many bottles/3 hours. Usually 2 is enough for me in the PNW. If I notice I'm not drinking as much as I should because I'm not thirsty, I take an Endurolyte. I keep them in one of those plastic coin purses up my shorts leg so I can get them out with one hand and my tongue. If I notice my stomach isn't emptying like it should, I take an Endurolyte. If I feel like I'm getting dehydrated, I take an Endurolyte because that means I haven't been as thirsty as I should have been.

So drink to thirst, and stimulate thirst with Endurolytes.

I think it's great that Hammer provides a method of decoupling liquids and electrolytes. Each person needs a different combination, and will also require different combinations in different conditions. I take an average of 1/hr.
