I'm leaning towards 12 week plan and just accepting what that yields at Boston.
No in my opinion. Your ROI is likely to be bigger just doing the 18wk plan for your marathon and trying to run well since the 6wk bike focus block is going to give you a slight FTP boost if it goes well, but after you are just going to look to minimize damage until May until you are recovered from the marathon. If you are deadset on executing the marathon plan than accept it.
In terms of Arizona, you obviously run well and you know you are basically trading a few minutes at Boston for potentially/most likely much bigger minutes in Arizona
(especially if the bike is not currently your strength
). So from Oct-May when you could be looking to boost FTP by 5-10% depending on how well trained you are, you are just going to sit on it until spring and lose some bike fitness and then look to ramp up. Just know that your Ironman time will almost definitely be slower than if you had trained properly from Oct-May. You'll still have some good fitness in your legs, but your bike power will not be what it could be.
