I have been really paying close attention to these hydration mixes this year with my marathon/ultra marathon training because what i am using to supplement now, I would like to take into the backcountry this fall. I have found that not all hydration mixes are nearly the same and some I dont think you are getting enough bang for your buck.What hydration powder mix is everybody using in the backcountry? I’ve used Nuun for the past few years, but have heard good things about MtnOps and a few others, curious if anybody has any opinions.
