Ironman Arizona 2007.
I don't know where the seed for doing this race was planted (Shelley??) (not for me, of course, but Don, but now that you mention it, maybe me??). Anyway, looking at the race courses, I was laughing out loud about the fact that most of the time I spent in Mesa/Tempe/Scottsdale revolved around the areas mentioned in the bike and run course, and I saw Tempe Town Lake and could figure the course there too.
I don't know how they do it there. It is such an urban area, I am amazed they can pull this off. Who knows? It may be in the cards to go back again next year.
Not that I would mind.
