Trying something new

I've been reading about the importance of proper hydration and eating to support running. Up until yesterday I would do my 1 - 2 miles each morning fortified with nothing but a half cup of coffee. I've been experimenting with small snacks, yesterday I had some wheat crackers before my run and I felt much more energized. Today I drank some extra water before my run and ate half of a low fat low sugar granola bar before running. I ate the second half after with the rest of my coffee. I think there is a difference in terms of the pace I can maintain.
