Use a hard 20-minute test to set practical HR zones.
Zone 2 HR
LTHR-based zones from a hard 20-minute average HR.
| Zone | Range | Use |
|---|---|---|
| z1 | 0 - 134 bpm | Recovery · Easy shakeout |
| z2 | 134 - 150 bpm | Aerobic · Long runs, base building |
| z3 | 150 - 156 bpm | Tempo · Comfortably hard |
| z4 | 156 - 168 bpm | Threshold · Intervals, race pace |
| z5 | 168+ bpm | VO2max / Hard · Short hard efforts |
Zone 2 target: 134 - 150 bpm. Keep easy runs below 150 bpm.
Formula: Z2 is 80%-89% of this LTHR estimate. Saving converts it to an estimated max HR separately.
