On the typical metric ride, I drink one container of Gatorade G2 before our break, which is usually around mile 30 or so. Then, I refill with standard Gatorade, after drinking one bottle at the break. So depending on the heat, it usally sums up to 2&1/2 to 3 bottles (the larger ones), give or take. The good thing is that Gatorade is almost always on sale for a good price.
