I bought this because it is going to be on the NYC Marathon course and I wanted to get used to it beforehand. I have used it on all of my runs, biking, and working out. The flavor is very pleasant (watermelon), the powder means I can make it the way I want to, and I don't throw out countless gatorade bottles. This is a product that I will buy in the future after the marathon for my general workouts and training. Big fan!
