Rob,

Sorry for the additional reply but I was looking around and found this:

http://www.wvmtr.org/electrolyte_replacement.htm

I'm sure there's a lot of people here who know a lot more about this than I do,
I consider myself to have mostly been lucky with my replenishment choices rather
than knowing a lot about it.

As a neophyte brevet rider I'd love any other references like the one above to
educate myself.

Fred,

Apologies. I am not sure I understand this:

"Another thing to consider is that if you are taking electrolytes (my
endurox bottle does not list calcium), it is theoretically possible
that you can displace the levels of available calcium in your system
because of the replacement of potassium and other cations, and lack of
calcium replacement."

Can you elaborate (and perhaps simplify this for a dolt? (me))
