Has anyone tried this while biking yet? I am looking for lower calorie alternative to my current sports drink and gel combination. I don't need the calorie and corn syrup on the gatoraid and propel. They also have an after taste that gets to you after drinking it during long (4+ hrs) rides. I found the PowerAde Zero over the weekend at a grocery store. Not sure if I can find it locally. It is made with a sweetner and 0 cals, 0 carbos and decent amount of sodium and potassium. Two key electrolytes. Plust B-12.
