I was on a recent hike with one of our local clubs. We gained over 4,000 feet elevation and I started cramping up at the summit. I was really concerned about getting off that mountain. After all, I had a full quart of Gatorade®* in my water bladder. A fellow hiker had some elete with him and gave me a drink, probably about a half pint. I kid you not when I tell you that the cramps instantly went away and I was able to continue on. I firmly believe in this drink and will use it from now on.
