In terms of my race goal, it's to have the overall best time. I've somewhat conceded that my swim won't be great and therefore I don't think putting the majority of my training time into swimming to potentially save 5-10 mins makes sense. I'll make sure I'm fit enough to finish the swim and not be completely cooked, and then try have have a strong bike and run.
ianpeace is a really well known, very experienced triathlon coach who has coached many AGers and world-class elites successfully. I think he would qualify as the type of person you want input from, and sounds like he gave it to you.
His advice is literally spot-on, as I'll repast word for word:
"To answer this question directly - no, I would argue it's not a good idea for training for your triathlon, and it's not a good idea if you were just training for a marathon. In order to address how your training should be rolled out a coach would need to first identify your goal for this triathlon. "
And to make it even more apparent why he'd say something like that, quite a few sub 2:45 marathon runners who make the jump to IM get crushed on the run, with 3:45+ hr IM runs. Obviously this has nothing to do with their lack of running prowess/background, and everything to do with overbiking for their bike fitness, and just as importantly, underestimating how much of a toll a 80-120 min swim takes on them with their lack of swim background and huge underemphasis on swimming. Going in with poor swim fitness doesn't just lose you 10-15mins on the swim, it loses you 3-5x that in the back end of the race.
I'll also recomend you do what Tom_hampton recommends above - get ANY plan (or better yet, several of them - you can buy 3-4 books on Amazon with full IM plans for like $80 total) and pick one that suits you ability and schedule. If your training looks really wacky compared to their recs (am I'm sure it does, with 3 hard tempo runs per week which NO plan I've seen recommend), you probably should reconfigure.
