Jonesing for the next big thing

Here I am, 11 days post Ironman, still eating like I'm training for Ironman and more importantly wallowing in melancholy. I know the diagnosis: I'm jonesing for the next big thing. If I could sign up for a marathon, or a half-Ironman or something that requires substantive training all would be right with the world. Alas, with my knee kaboshing any ability to run, my plans to race a marathon in October in quest of a qualifying time for Boston are hopelessly lost. Woe is me.
