At my pace, water stops a mile apart are too far. I breathe through my mouth, and hate when it gets dry, so I like being able to sip from my Camelback. Actually, though, I have a waist pack with a diagonal single bottle and a little pouch for gel or whatever.

But at Wickham Park Marathon, I'll be carrying 100 oz of water and praying it makes it through a 3.75 mile loop...
