14 miles by bike is longer than you think....when I started, I took two weeks and increased how far i rode by a mile on the way out until I was easily doing half of my expected daily commute. Then I went for it, of course I'm only doing 14 miles (roughly) total.

Either way it is your rear!

For breakfast, I have a package (just one) of instant oatmeal. YMMV as I only go about 7 miles. As for water, I don't take any for anything less than 10 miles (flat).
