MFR 67: The Goldilocks Principle of Hydration for Runners
If you’re running a 5k on up to a half marathon, hydration matters, but it’s not terribly tricky. The focus should be on making sure you consume enough fluids to prevent dehydration,but if you’re out there for several hours – or a lot more – you need to be even more concerned about avoiding over hydration, also known as hyponatremia. Hence the Goldilocks Principle. You must make sure you drink enough, but if you drink too much, you’ll be in big trouble.
