It is not considered a 'dry' run if you are already
well-hydrated to begin with.
Just water parade about 30-45 minutes before an extended run,
and you'll find that you can last a long time without further
rehydration. When you're running, control your water intake to
small, regular amounts (say, one mouthful every few minutes).
Simply put, your body can absorb small, regular doses of water much
better than a whole torrent at one go.
I'm not telling you to ration your water; I'm telling you to use
it more efficiently.
And seriously, I still find it very difficult to understand why
it is easier for you to carry one liter of water than one liter of
air. I can imagine that that the water in that bottle of yours will
slosh around uncontrollably as you run - how is that any easier
than running with an empty bottle?
And as for your backpack..... just get a backpack with
compression straps.
There. Just think simply, and your problems become really
trivial.

i get your point... and i did not say that i drank 1liter of
water at one go..
i find that carrying and drinking about 1liter of water bit by
bit keeps the thirst away well..
i also did not say that carrying 1liter of water is easier than
1liter of air..
just want to see if there are ways to not carry a bottle of air
in my hands or in my bag......
can use the free space to carry/put more stuff what.....
hellokitty, yes schoolbag.. i carry the same water bottle i use
for jogging in my schoolbag..
