    Hi there,

    I am running with a Stryd Power pod and purchased a 50mile/100k powerbased plan.
    I have a question about zone 4.
    In your resource about “Understanding Your 8020 Run Plan”, you said that zone 4 is the narrowest zone. But the range for running power zone 4 is 102-120% of rFTP.
    I wouldn’t say this is a narrow range.
    Can you explane this for me?

    Thanks for pointing this out. This line is a relic from when our plans were only HR-based. You’ll see that Zone 4 for HR is only 3 units. We neglected to update the document when we rolled out the Pace and Power plans which have a much broader Zone 4.

    I’ve removed that line from both our Run and Triathlon Understanding documents.

    Let us know what else you find in our documentation! WE appreciate your help in keeping the resources updated and accurate.
