I am trying to figure out which Heart Rate value to use when I training outdoor since I don’t have a Power Meter. I have completed the Full Frontal last week. My new HR values
Max HR is 180
LTHR is 168
When a outdoor work out say:
Effort: 8 minutes @ RPE 6 – 80% of FTP – HR <90%
Recovery: 12 minutes @ RPE 2.5 – 55% of FTP – HR <75%
Do I use my Max HR or LTHR HR to set the heart rate for the workout.
Max HR would be 162bpm
LTHR would be 151bpm
That is a big difference on effort between the two HR.
Any help would be greatly appreciated !
