When going above an hour, do you run with a bottle, @heywoodu?
I'm starting to get to the point where I need to consider hydration and nutrition during the run, and haven't quite figured out how I'll do it yet.
I have a belt with up to 4 small bottles and did my first test using 2 today. 2 isn't much of a problem, but when using 4 I think it'll be rather irritating.
