What sort of food stash would you carry on your bicycle? When I have toured, my cycling partner and I have carried an extra meal with us (i.e. packaged noodles), and maybe a few bits and pieces like coffee, sugar, or lemon spread ...... but we have bought our day's food along the way.
Why carry food when there's a good chance you'll encounter a store at some point during the day? I could see it if the tour was somewhere really remote ....
