On an easy run, let comfortable, conversational effort lead; use a personal heart-rate zone when your zones are configured and heart-rate training is your method. On a tempo run, follow the planned pace or heart-rate target. During intervals, keep each repeat’s prescribed pace or time/distance and the recovery interval visible. Review Training Effect and other estimates after the activity, rather than letting them override the session you intended to complete.
| Workout | Primary field during the run | Useful context | What to review afterward |
|---|---|---|---|
| Easy run | Effort, conversation, or your configured heart-rate zone | Elapsed time and pace | Training Effect and how controlled the effort felt |
| Tempo run | Planned pace or planned heart-rate target | Lap time, distance and heart rate | Training Effect alongside the completed workout structure |
| Intervals | Repeat pace, duration or distance | Recovery duration, pace and heart-rate response | Aerobic and anaerobic Training Effect; investigate mismatches with the planned session |
Which metrics should be on an easy-run screen?
An easy run is defined by restrained effort, not by hitting a universal pace. Garmin describes Zone 2 as a comfortable intensity at which conversation is possible, associating it with basic cardiovascular training and recovery. That description is a useful check: if you cannot speak in normal sentences, the run may no longer be easy for you, regardless of what the pace field says.

Use effort as the deciding signal
Put elapsed time first, then heart rate or heart-rate zone if you deliberately train by heart rate. Pace can remain on the screen as context, but it should not force the workout faster when hills, heat, wind, footing or fatigue change the external speed. A flat 6:00-per-kilometre run and a hilly run at a slower pace can represent the same easy effort for one runner; the number alone cannot establish that.

Garmin’s zone labels depend on how maximum heart rate and zones are configured on your device. Before relying on a zone alert, check that your maximum heart rate and zone method reflect your current training approach. Garmin’s broad descriptions make Zone 2 comfortable and conversational; Zone 4 is fast, somewhat uncomfortable and accompanied by forceful breathing. Those descriptions are guides, not a universal easy-run threshold or a prescription for every athlete.

A practical easy-run display
- Elapsed time, so you can complete the planned duration without chasing pace.
- Heart rate or heart-rate zone, when internal-effort control is your chosen method.
- Current pace as a secondary reference for terrain and conditions.
- Lap or interval information only if the run includes a planned progression or strides.
If you are not using heart-rate training, hide the zone field and use conversation and perceived effort instead. Showing a target you do not intend to follow adds distraction rather than control.
Should you use pace or heart rate for a tempo run?
Use whichever target your training plan prescribes. A pace-based tempo should show current or lap pace prominently; a heart-rate-based tempo should show heart rate and the relevant zone. Do not switch targets merely because another metric is available.
When pace is the planned target
Use lap pace or the workout’s repeat pace rather than relying only on overall-average pace. Average pace includes warm-up, recoveries and slowdowns, so it can conceal whether the sustained tempo segment was executed correctly. Keep elapsed time and distance visible to confirm the length of the work block.
When heart rate is the planned target
Heart rate reflects internal response and may rise during a continuous effort even when pace is steady. Use the target range from your plan, allowing for the normal delay between increasing effort and seeing heart rate respond. Conditions such as heat and hills can make a heart-rate target more informative than a fixed pace, while a pace target can be more practical when heart-rate data is noisy.
How Garmin Run Coach describes target modes
Garmin’s Run Coach documentation says its Auto workout target mode uses pace for tempo and threshold workouts, and heart rate for recovery and base workouts. That is a description of that feature’s target logic, not proof that every Garmin watch, plan or runner should use pace for every tempo. If your individual plan specifies heart rate, follow that instruction.

- Optional current pace or heart rate as a cross-check, not a competing target.
After the run, compare what you actually completed with the planned duration, pace or heart-rate range before interpreting any score. A Training Effect value can describe the estimated stimulus, but it cannot tell you whether you followed the workout’s intended structure.
What Garmin metrics matter for interval training?
Intervals require a repeat target and a recovery target. During each hard segment, prioritize the prescribed pace, duration or distance. During recovery, make the recovery duration or distance visible and observe whether your effort comes down enough to start the next repeat as planned.

Use lap pace for pace-based repeats, or a countdown of the work interval when the prescription is time-based. Overall-average pace is a poor control field because easy recoveries and warm-up dilute it. If the workout is distance-based, keep lap distance visible so you know when to stop the repetition.
Make recovery explicit
Recovery is part of the workout, not dead space between efforts. Display recovery time or distance and, when useful, heart rate. A heart rate that remains high can explain why a later repetition feels slower, but do not delay every repeat simply to force a particular heart-rate number unless your plan says to do so.
Why the post-run label can surprise you
Garmin’s Training Effect analysis uses heart rate and speed. Garmin notes that if heart rate does not come down during an intense interval session, the activity may be labeled “Tempo” rather than “Threshold.” That label explains the device’s classification; it is not an instruction to chase a category while you are running.

- Optional repetition count, if your workout profile provides it.
Short, high-intensity repeats can add anaerobic Training Effect, while the total session also contains aerobic work. Garmin’s examples are illustrative, and your result can differ with training history and other personal factors.
How to interpret Garmin Training Effect after a workout
Training Effect is an estimate of an activity’s impact on aerobic and anaerobic fitness. Garmin states that it uses profile information, training history, heart rate, duration and intensity. Aerobic Training Effect is mapped to a 0-to-5 scale using excess post-exercise oxygen consumption (EPOC) and the device’s fitness and training context.
Use it as context, not a quality grade
A high number does not automatically mean a better workout, and a low number does not prove that a session failed. The score describes estimated physiological impact. Judge the activity first against its purpose: an easy run should feel controlled, a tempo should contain the planned sustained work, and intervals should match their repeat and recovery design.
Allow the estimate to learn
Garmin warns that results can be atypical while the device learns your parameters and that multiple sessions may be needed for more accurate results. Treat an early or unusual value cautiously, especially after changing your maximum heart rate, profile information or training pattern.
Read aerobic and anaerobic effects together
Intervals may produce a noticeable anaerobic contribution while still generating substantial aerobic work. A continuous tempo can emphasize aerobic impact without being a “better” or “worse” score than intervals. Compare sessions with similar structures and conditions rather than ranking unrelated workouts by one number.

What is Performance Condition, and should it control the run?
Performance Condition is a real-time comparison with your established baseline fitness. Garmin says that during the first 6–20 minutes of a run it analyzes pace, heart rate and heart-rate variability (HRV). The displayed value represents deviation from baseline VO2 max; Garmin describes each point as about 1% of VO2 max and uses a range from -20 to +20.
An established VO2 max and heart-rate data are required. Use the value as an early context check: a persistently negative reading may support easing back when your effort also feels unusually hard, while a positive reading does not require you to accelerate beyond the day’s plan. Performance Condition is not a replacement for the easy, tempo or interval target.

Garmin lists up to eight running-dynamics metrics: cadence, ground contact time, ground contact time balance, running power, Step Speed Loss and percentage, stride length, vertical oscillation and vertical ratio. Availability depends on the watch model and, for some fields, a compatible sensor.
| Metric | What it represents in practice | Best use | Important limitation |
|---|---|---|---|
| Cadence | Step rate | Observe how it changes with pace, hills and fatigue | No universal cadence is correct for every runner |
| Ground contact time | Time each foot spends in contact with the ground | Trend changes within comparable sessions | Affected by speed, terrain, fatigue and running style |
| Ground contact time balance | Left-right contact-time distribution | Notice persistent asymmetry worth discussing with a professional | Single-run variation is not a diagnosis |
| Running power | External running-power estimate | Follow a power-based plan when your watch supports it | Availability and calculation vary by model |
| Step Speed Loss and percentage | Speed change associated with a step | Optional advanced observation | Requires HRM 600 in secure mode paired with a compatible watch |
| Stride length | Distance covered per stride | Compare at similar speeds and terrain | Changes naturally with height, pace and fatigue |
| Vertical oscillation | Up-and-down movement of the body | Observe personal trends, not a target number | Interrelated with other dynamics and running conditions |
| Vertical ratio | Vertical movement relative to stride length | Context for comparable efforts | Color bands are comparisons, not an injury screen |
Why dynamics should stay secondary
Garmin explicitly says running-dynamics metrics are interrelated and affected by pace, runner height, inclines and declines, warm-up and fatigue, and individual differences in running styles. That makes them useful observations but weak universal grades of form. A change after a hill or late in a long run may describe the conditions rather than a technical problem.
When the HRM 600 matters
The Garmin HRM 600 is an optional path for runners who specifically want Step Speed Loss and have a compatible watch. Garmin says the strap must be paired in secure mode for that metric. You do not need a chest strap to track ordinary pace, workout targets or every running-dynamics field. Check current watch and sensor compatibility before buying, because availability can change.

How to use Garmin’s running-dynamics color gauges
Color gauges for cadence, vertical oscillation, ground contact time, ground contact time balance and vertical ratio compare your values with those of other runners. Garmin says the analysis used hundreds of runs and selected representative, steady, self-selected overground runs without significant elevation change; subsequent analyses included only runs faster than 7:00 per kilometre (11:16 per mile).
Those are study-method details, not an ideal range for an individual. Do not treat a green, yellow or red band as proof of good form, poor form or injury risk. Compare your own values in similar conditions, and investigate only persistent changes that coincide with symptoms, unusual fatigue or a meaningful change in training.
Setting up a focused Garmin data screen
Menu names differ by watch model, but the workflow is generally the same: open the Run activity, enter its activity settings, choose Data Screens, and edit the fields for the pages you use. Keep one page for the workout target and a separate page for optional context so secondary numbers cannot compete with the main instruction. Pair any required sensor before the activity and confirm that the desired field appears on the watch.
- Choose the Run profile you use for the session.
- Open its activity settings and the Data Screens editor.
- On the primary screen, place only the target metric, elapsed or lap information, and one response field.
- Create a secondary screen for heart rate, pace or dynamics that you may check without making it the goal.
- For intervals, verify that lap or workout alerts show the work and recovery segments you planned.
- After saving, run a short check and confirm that the fields populate with your watch and sensor combination.
If a field is missing, consult the exact manual for your model. Garmin feature availability is model-dependent, and a metric listed in the platform documentation is not guaranteed on every watch.
Quick Recap
A simple decision rule for every session
- Easy: protect conversational effort; use configured heart rate if that is your method, with pace only as context.
- Tempo: execute the plan’s pace or heart-rate target using lap information.
- Intervals: execute each repeat’s pace, time or distance and display recovery.
- Afterward: use Training Effect and Performance Condition to add context, not to rewrite the workout.
- Running dynamics: look for personal trends under comparable conditions; never chase a universal cadence, ground-contact or vertical number.
