Thanks for all the input ladies. I have signed up for another relay triathlon - this time its 14 miles. I think I'm going to take the average of all of your advice - keep riding my bike and get better endurance and technique for a little while longer, then get a road bike. I saw the Trek Madone 4.7 and I swear angels sang and a glowing light came from it. Why do I have the champagne taste?!?! Perhaps I'll start with a road bike not quite so expensive - maybe an aluminum body with just a carbon fork. We have a bike shop near our house that rents out bikes. The hybrid they rent is also a Trek FX. I'll try some of their rentals as well. Will wait and see in about 6 months. As for now, I'm addicted!
