Carrying water on long runs

[Bikingmomof3]

I carry a water bottle that has a hand strap on it so I don't actually have to hold it. It's great. I tried the belts and packs around the waist and back and they really bothered me. I carry it with me for any run over 6 miles or if it's over 85 degrees out.

Limewave,
Which one do you use? Even with the cooler weather, I am always thirsty. Partially because my medications make me thirsty, the other I sweat a lot.
TIA!
