Holy shit; that’s an insane bike time. How long did it take to get to that point? Was it a lot of just base and sustained power builds then? I thought my half bike times were decent but you must be sub 2 houring your half bike splits to hit that time.
What swim and runs are you sourcing from? I actually wonder if your training style is more like what I should consider doing. I find myself doing pseudo trainerroad plans but Frankenstein it a bit; this year I might try doing swimming on my own just because I have to get up so early and my masters group ends slightly too late for me.
