I usually
buy camelbak at Target and they are always like $ 15!
I also carry a lightweight 70oz hydration bladder in my day pack, like the one
by camelbak.
I also had 500 ml of coconut water diluted with water in
my camelbak which I take on any run over 7 - 8 miles.
I see
your camelbak there.
I trained for MCM last year with
my camelbak and surprisingly hated it this year.
