> that is outdated advice. for one, some people sweat more than others, the salt levels in the sweat is totally different too.

People forget that. They just follow "salt is killing you" advice, meanwhile I sweat salt like it's water. Last race I did had the sense to add salty potato chips to their rest stops... I didn't cramp up.

Meanwhile Gatorade is absolute trash for electrolyte maintenance for someone like myself.

The people drinking a gallon of water (not fluids, just water) a day are often flushing out electrolytes. There are a lot of things you might expect a doctor to yell at you about in an ER but from what I understand coming in with heart palpitations triggered by low potassium due to over-hydrating is a good one.
