I liked the quote from your website ... "Of course, dehydration is
often associated with higher electrolyte (including sodium)
concentrations, which makes the common appearance of hyponatraemia
seem surprising."
It is surprising to me - which is why I first asked the question.
It's not really that surprising. If you lose a lot of water alone, your
salt *concentration* is bound to rise. Now you will normally always lose
some salt as well but because of the greater water loss, the concentration
of salt in your plasma will still rise, but less so. Your total body salt
will have dropped though and when you replace all that water you'll now be
in the dangerous position of having too low a concentration of salt in your
blood (and brain).

am not a troll or idiot. I am an experience marathoner and endurance
athlete.
Well we know that *now*. ;-) Doug can be forgiven raising the troll issue
though because it is a subject that comes up very regularly here. That
said, the parlous state of this group these days because of troll activity
has made it much less attractive source of information.

It seems as though all websites I found were related to ULTRA
endurance activities - 4-8-12-24 hours in length but my post
originally was about a simple 30km or so running race - <2 hours or
so.....
No it wasn't. You never mentioned distance in your original post.
Quoted message said:It would still seem to me that salt tabs would INTERFERE
with hydration in these shorter events so I was looking for people's
knowledge on this.
Why do you think that? I'm not saying you need salt for shorter distances
(if you're running in Death Valley all bets are off) but it's pretty well
accepted that having a bit of salt along with your sugars helps absorbtion.
I've never heard of it interfering with hydration.
