Hi,
touring bikes give you a seating postion halfway between a road bike and a hybrid. They are intended to be ridden all day; and a good one will be comfy. Last fall I bought a 20 year old touring bike on an impulse, so they can be found. The Eighties was a good decade for bikes. Tubing and shifting got a little better. Later lawyers would force some changes in bike manufacturing; and not for the better. Seventies bikes have the advantage of being readily available and cheap. SOme of the bikes from the early Nineties (like the first Treks) are really sweet bikes.
Now, one thing you can do if you find a roadbike that fits is to buy a new stem. For $40 you can get a Nitto Technomics that will bring the handlebar up 2 or 3 inches, and back towards you about an inch or more. This can make a big difference in comfort. I also like shock absorbing bar tape. My 20 year old Fuji has 2 layers of shock tape, the top layer is this pretty tan Cinelli shock tape that fits the color scheme of the bike nicely. It also adds some needed comfort.
