Great Question. For Ironman, I stayed in zone 2 - 120 HR. I could have pushed it harder though. Again, great question. Would like to get ST wisdom on this issue.
same for me - zone 2 on the run - as much as I would like to run harder it never happens in an IM
in an open marathon I can run at threshold 169 bpm
in this year's IMs I averaged 148 (flat course slowest time), 141 (flat course with a bonk) and 148 (hilly course fastest time)
The bike is lower, about 138 although I ride to power not HR
