Ironman Louisville KY 2011

I'm using the Triathlete Essential Week by Week Training Book by Matt Fitzgerald. There are 10 levels of training plans for each distance. I'm in week 5 of the Level 7 Ironman Plan

Only 163 days left until IM Louisville!!!!! I'm curious if everybody has picked out their IM training program. I'm planning on using the Beginnertriathelete.com 20-week program. Any thoughts, tips, suggestions, input????
