Good advice. For an opposing perspective regarding 60 minutes: I've found that I can go without water or food for up to 2.5 hours, in the morning when the sun is just coming up. That's after a series of ~1.5 long runs without water. I usually do all my runs without eating anything beforehand, but for over 2 hours I'll have a granola bar and banana beforehand and drink plenty of water.
Obviously, do what works for you. Just laying out my experience. I used to carry water, gels, and all sorts of other stuff. Was eating every 20 minutes after 45 minutes in and the whole deal. Then one of my running partners showed me what was possible. Very freeing to just get out there. And, in my experience, your body adapts amazingly well and it carries over to the hunting context.
