I go through 25 fluid ounces of drink every 50 minutes. So I normally have two bottles on my bike and that gets me a tad over 30 miles. I personally won't ride 20 minutes without water. In the summer heat here one can die without staying properly hydrated. And getting dehydrated can cause you to mistake thirst and hunger as well as a lot of other things.
For rides longer than 30 miles, if I can fill my bottles somewhere with water, I take dry mix to put in them. When I can't do that, I've stuffed a bottle in my jersey pocket or velcro'd it to the underside of my top tube and even taped one to the underside of my downtube a time or two. Put that bottle in a plastic bag. It'll get all sorts of road filth flung onto it from the front tire.
So I have carried four 25 fl oz bottles on rides and could do 5 or 6 bottles if willing to deal with them in my jersey pockets. Those get switched out as soon as I empty the first bottle as the weight is annoying in a back jersey pocket.
So if you run out of drink while riding distances, you need to stop and call for your SAG person.
