    I did a metric a few weeks ago where I tried Gu Roctane for the first time. It has more than 2x the sodium of regular Gu plus added potassium (plus some other stuff - "Roctane Amino Blend.")

    I'm planning to use it for rides on hot days this summer, as part of electrolyte replacement.

    Magnesium, too. "Designer" sports drinks usually include some magnesium, but maybe not enough; convenient-store and homemade sports drinks usually don't have magnesium at all.

    I started getting night leg cramps when the weather turned warm (even though I was hydrating with Heed, which does contain some Mg). I added 500 mg magnesium daily to the 3:2 calcium/magnesium supp I was already taking, and the cramps went away.

    But then, I sweat. As I said last year - after a hard ride I like to jump in the pool to dry off.
