A long 23-ish mile trip on Thursday- lots of off-trail and lots of [bleep] trail, lots of elevation gain and warm (temps into the mid to upper 80's). Every other 16 oz bottle had a Nuun tablet. I was downing a 16 oz bottle approximately every hour, so staying at least slightly ahead of the hydration curve. It was a 12-ish hour hike, so roughly 6-7 liters total of water.

Nothing magic about Nuun, but it tastes good and provides 300 mg of sodium, 150 mg of Potassium, 25 mg of magnesium and 13 mg of calcium. It looks like it could be easily replicated for less money, but you just throw a tablet in AND it tastes good smile
