Those Jamis Auroras are supposed to be fine touring bikes- lots of people would love to get one but can't find any.

Hey, if your hybrid fits you well there is no reason you can't do long rides on it.
Plenty of women do centuries on their nicely fixed up hybrids. My DH loved to do 30-40 mile rides on his trek hybrid with albatross bars before he got his Rivendell. If your hybrid is a bit heavier than a speedy road racer, it will just make you a stronger rider.
