also if possible that your trail is out-and-back, or a figure-8 intersecting, consider the options of water bottle caching.
Sure there is the risk of someone stealing your water, I recommend using many small bottles, to reduce single points of failure. I like to wrap the bottle in brown paper bags. brown hides well with dirt. Also recommend you bring a paper map or GPS and mark the waypoints of your cache.
When hiding them, the cache spot always seems genius, and no one would ever think to look there... problem is that the trails often look different on the way back, and your memory will betray you. Hide it well, get creative, write it down, pick it up later.
Less to carry, and an ample re-supply plan. 8 oz every 1 mile works for me in hot weather.
