Reading Friel's power meter book again, I see he recommends using LTHR, rather than max HR to set zones. He also recommends using the average HR for the FTP test as LTHR. This seems to better reflect the numbers I see when riding, compared to percentages of max HR. Z1 is now below 140 bpm, whereas before it was under 110. The lowest I attained last summer was 120, and I was barely moving! I can hit 130 within just a few minutes of easy (to me) riding, and this always seems to have low perceived exertion.
