You can ride anything you want to, and they will work with/without flats, vibration, wrecks, instability, etc. But why you would do a through trip on road bike tires? Sounds like a good time to buy a hybrid bike to me. I ride 700c x 38's. I also have a 26" tire mountain bike with 1.5" wide semi-slick tires and a drop bar handlbar. Both are great for the Katy. You don't need anything fanc--just a sound tuned up bike that has good rubber and fits you good enough to spend 6-7 hours a day on it.
