This probably isn;t the answer you may want to hear, so I’ll apologize up front.
Your plate is pretty full My Friend, and I know you know that. Ironman is different things to different people however, may I respectfully suggest that perhaps this is a great season to focus on a number of local sprint distance events as opposed to Ironman?
Here is why I suggest this: Ironman, as I’m certain you are aware, is a great experience. It isn’t just about the race day- at least speaking personally- it is about the long preparation. It’s about all the things you already realize (otherwise you wouldn’t be asking this question): The very long rides, the long runs, the incredible fatigue after a good training day, the fear of realizing the enormity of the task and the sense of accomplichment at slowly rising to the goal, gradually, exhaustively, systematically. Unlike a lot of experiences in life it all culminates in one grand day, captured on video and film, that we can look back on for inspiration, amusement, reverence.
Ironman isn’t a quick fix, it isn’t a finisher’s medal and a tick off a “to do” list. Perhaps for some it may be, but that would be like expecting a drive through at a Wolfgang Puck restaurant. It might not fit.
Maybe Ironman won’t be an optimal fit for you this year. Now, I could be off base with this and you may very well be an incredible efficient multi-tasker and time manager. I’m not. Getting ready for Ironman to me is a huge undertaking. It is nearly a year long commitment with all the chips stacked on one day. That’s tough.
If you go for it, I admire your drive and chutzpah but I empathize with your pain in those last 10 miles of the run. If you decide to come back and race another year I admire the wisdom and humility and respect for the sport in that decision too.
Either way My Friend, I wish you the very best of luck. Please keep us posted on your decision and how things are developing.
