Thank you to everyone for giving me such good advice. I have considered IM AZ, but I think that it will be difficult to register this year since there will be participants registering for the 2009 race after both the April/Nov events. There may not be very many slots open after returning athletes register. Right now, I am leaning toward IM Louiville since I would prefer not swimming in the ocean, I am strong on the hills on the bike, but weak on the hills for the run, so the course sounds perfect. The only drawback for me is the time of year. I have two young children, so the bulk of my training will be before school starts. My husband is supportive of my quest to become an Ironman (IronMom), so we will find a way to work this out. I am also considering the Great Floridian (thanks JmcG), I really like the coarse and the time of year the race falls. It also looks like it will be easy to get into. Right now, my plan is to try and register for Louiville, but if I can not get into that race, I will register for the Great Floridian. Again, thank you so much for all your advice. It really has helped me make my decision.
