How each Garmin analyzer number is worked out
Dates use the local time your watch recorded. Missing values show as unavailable, never zero.
The numbers
| Metric | What it shows | How it is worked out | Watch out for |
|---|---|---|---|
| Pace | Time per kilometre | Total time ÷ total distance | Not the average of each run's pace |
| Splits and fastest km | Your pace each kilometre | Time between distance marks, estimated between samples | The last split may be short |
| Heart-rate zones | Time in each zone | Garmin's own zone times | Zones may have changed since |
| Training load (7-day) | Recent effort | Sum of Garmin's load over 7 days | Not Garmin's Acute Load |
| Fitness, fatigue, form | Long and short load trends | Averages over 42 and 7 days. Form is fitness minus fatigue. | Estimated from your load. Not a fitness or readiness score. |
| Load ratio | This week against the last four | Last 7 days ÷ the 28 before | Needs 35 days of data. Not an injury risk. |
| VO₂ max trend | Garmin's fitness estimate | Rolling 28-day median | An estimate, not a lab test |
| Sleep | Length and stages | Garmin's values, filed under the wake-up date | Watch and wear time decide what exists |
| HRV | Overnight variability | Garmin's nightly value and baseline | Compare with your own range only |
| Body battery | Energy through the day | Garmin's values | Garmin's model, not a measurement |
| Efficiency | Speed per heartbeat | Average speed ÷ average heart rate, first half against second | Heat and hills change it. Hidden on interval sessions. |
| Records | Best efforts | Fastest stretch in the tracks loaded here | Short efforts are approximate. Not official bests. |
