So I completed my first 140.6 this passed weekend at IMWI (last year, I attempted but DNF'd at mile 18 of the run). I do work with an excellent coach and we are working on my cardio base but it is just simply not where it needs to be. I biked and 8:15 on Sunday with an average HR of 164 bpm for the 112 miles with a max of 189bpm. My power was also pretty low but my heart rate is really what holds me back. My question for all of you is what was your average heart rate on the bike of a 140.6 and has anyone else struggled with consistently high heart rates on the bike and had results lowering it? I just so badly want to not have to be that person that is constantly skirting cut offs and need to hear from others that have been there.
EDIT: It seems I did not add enough information to the this post originally. I am a 26 year old female. I do have HR zone they are as follows:
Zone 1: 119-150 bpm
Zone 2: 151-162 bpm
Zone 3: 163-170 bpm
Zone 4: 171-181 bpm
Zone 5a: 182-85 bpm
