“Easy running” names an intention, not a guaranteed intensity. An activity can be relatively hard for one person and moderate for another. A high zone label alone cannot tell you why a particular run feels difficult.
Is the effort itself hard, is the watch showing a different zone than expected, or both? Those are different questions. A device-setting explanation cannot diagnose symptoms or explain every high reading.
02
Describe effort without assigning a zone
Speech is one rough clue: needing frequent pauses for breath while talking can indicate vigorous effort. That does not translate into an exact five-zone label. Do not keep exercising to complete this worksheet if you have concerning symptoms.
03
Follow the matching next step
For a label mismatch, check the device settings and the calculator method. For unexpectedly difficult activity, symptoms, a condition or medication-related questions, seek qualified advice rather than forcing a number.

An estimated range starts with assumptions.

Find the inputs and method before treating an estimate as a target.
