How do you carry water when you go for longer runs? I don't usually bother with water but I'm upping my distances and long runs are now getting into the 1.5-2 hours area, where I feel I should be having a small amount to drink along the way. I don't really like the idea of the handheld bottles - I already use a handheld phone strap. Those bumbag type belts you attach small bottles to look quite practical but I'd worry about them bouncing up and down - do people find that happens? Or I've heard some people use flipbelt-style fabric belts and you can squeeze a small bottle in there, is that not too difficult to get the bottle in and out of while running? Any other good solutions I'm missing?
