Words are inadequate

If you don't plan to run for more than an hour, drinking before you go out is the best idea. Hydrating yourself for 24 hours up to the run will cover you for that length of time. But don't chug before you step out the door - your stomach will be full before the walls can absorb all the liquid and the physical exhaustion will make you naseuas.

If that doesn't work, then leave a cup of water in a "hiding place." Under a tree is fine, but keep it away from four year olds who might mistake it for litter or a play toy. You don't even need a water bottle, an expendable plastic cup (you will lose a few as you look for a hidden enough spot) is fine. Then try and find a loop where you can cross it every 20 minutes or so. The right route can make a large difference (beyond water, cement vs gravel vs dirt and hills mean more than you would think).

As a soccer player, we just took water breaks and headed to the sidelines, but this is what my Dad did, and he ran a marathon, so it should be good advice.
