What Is this Field in the Activity Power Tab: "Power @NNN bpm XXXw"?

Training

Hi Alex,

Not sure I have all the answers, but I think:

  • More likely to align with LT1 in the 3 zone model
  • Subject to the above being correct, LT2 is close to FTP/CP
  • I track the information over time to see if I am increasing my aerobic base (narrowing gap between LT1 and LT2)
  • If LT1, in the 3 zone model then this would be a beneficial place to spend time during an “endurance ride”
  • I use the HR vs Power graph in the compare functionality to review increase in aerobic base over time

Good thread here that talks about LT1 etc and its alignment to 7 zone model etc including some good links to an excel to show your estimated LT1 etc: Mapping 7 Zone to 3 Zone Model Wrt Polarized Training

My 2 cents :slight_smile:
