Yup that's what I've read in sportscar. Hydration requires moving water and out and one of them requires some potasiums.
As far as the gatorade etc, I go by what we were told in wildfire training - always cut them at least 50/50, 2:1 or 3:1 is better. Got to figure that's no BS. Everything in that training is to make sure we all walk in, get the work done, and walk out on our own.
