From reading the excellent Runner's World -'The Runner's Body' book I understand that unless you drink too much fluid (most of us don't) then your sodium concentration goes up during long periods of excercise, because you lose more fluids through sweating than salt. And it's the concentration of sodium, not the overall mass that's important. So replacing 'lost' salt during, or even after long runs is not necessarry (there's enough salt in our regular diets to bring the overall mass up to normal levels). This is all despite the sports drinks industry trying to make us fearfull of losing too much and we must pay for special products to prevent disaster.

That all depends on how much water you are drinking. The current trend is to drink to excess and not to follow your thirst which dilutes your blood.

Especially as the more you drink, the more you pee.
