All About Metrics on ErgZone
To help athletes reach their goals, the ErgZone app calculates and displays more than 15 different metrics.
In this article, we list and describe the metrics available on ErgZone.
Performance data can be viewed on the ErgZone app and on the ErgZone Web Admin during and after the workout has ended.
ErgZone App
Workout Screen
The screen you see when you click on the "Connect" button on a workout is called the "Workout Screen", it displays a table with 3 sections: Header, Overall/Current Data, and Intervals Data.
Header (pink)
The 1st line of the table is called the header and displays the name of the metrics.
Click on the columns' header to change which metrics should be displayed. This video demonstrates how it works.
Overall (blue)
The 2nd line of the table is the Overall Data or Current Data.
The first column will always display progress as a percentage from left to right.
This line displays the current data during the workout, the same information you'd see on the PM5 monitor.
When the workout is done, it will display the average or total overall, depending on the metric.
Learn more about it in the Available Metrics section, where we describe each metric in detail.
Intervals/splits (green)
The 3rd and subsequent lines display data for each interval/split.
The first column displays the interval number inside a circle; as you progress on the interval, the circle will change color to represent it.
In portrait mode, the app will always display three (3) intervals: previous, current, and next. In landscape mode, thirteen (13) intervals are displayed.
The ErgZone app will automatically scroll down the screen to display the current interval.
Available Metrics
Time
As the name suggests, the Time column will display the duration when selected.
While you work out, the Time column will display slightly different data depending on whether the workout is set for "Time," "Distance," or "Calories."
Workout for time
3x 1:00 min ski - 0:30 seconds rest
During the Workout | After the Workout | |
Overall | Total time (does not include rest). | Total time (does not include rest). |
Intervals | Time remaining to finish the interval (does not include rest) |
Total interval time (does not include rest). |

Workout for distance or calories
3x 100 meters ski - 0:30 seconds rest
or
3x 10 cals - 0:30 seconds rest
During the Workout | After the Workout | |
Overall | Total time (does not include rest). | Total time (does not include rest). |
Intervals | Total time (does not include rest). | Total interval time (does not include rest). |

Projected (Projected Time)
Available on workouts for distance and calories, it displays the projected time until the end of the interval and the workout (overall line). The calculation is based on the current pacing.

Elapsed (Elapsed Time)
Similar to Time, but Elapsed Time included the rest period.
Meters
Displays the distance (in meters) overall and per interval.
Watts
Display wattage.
If a suggested wattage is set for an interval, the column watts will display the differentials, it includes the suggested watts and the difference between the suggested and actual.
Before start | During the Workout | After the Workout | |
Overall | - | Current Wattage | Average Wattage |
Intervals | Suggested Watts, if present. | Suggested Watts and differential | Average Wattage and Difference |

Cal/hr
Calories per hour.
During the workout, it displays the current data.
After the workout, it displays the average per interval and overall.
/500m or /1000m
Pace for 500m for RowErg and SkiErg.
Pace for 1000m for bikeErg.

The Results Screen
Heart Rate (HR)
HR Colors (Zones)
Colors represent Heart Rate Zones as follows:
- Grey: Bellow 60%
- Blue: 61-70%
- Green: 71-80% green
- Orange: 81-90% orange
- Red: 91+ red
The rings' colors represent time spent in each zone and are ordered clockwise.
The zone you spend the most time in is the one that starts at the 12-hour mark.
While working out, your current zone will be displayed thicker (bold).
Can I customize my HR zones?
Not yet, but we will add that option to the app soon.
Can I see the HR average instead of the final HR when the interval ends?
Not yet, but we will add that option to the app soon.
Displaying HR% during and after a workout
You can set a Maximum (max) Heart Rate.
When Max Heart Rate is present, ErgZone will display HR% during and after a workout.
Updating Max Heart Rate:
- On the ErgZone app
- Go to "Settings" (gear icon on the top left of the ErgZone app)
- Scroll to the Heart Rate section and provide your MAX Heart Rate.
Note: Your HR% will be calculated considering the Heart Rate Reserve formula if you set Resting Heart Rate.
Displaying HR instead of HR%
If you set MAX Heart Rate on Settings, ErgZone will display HR% instead of BPM.
To ensure BPM is displayed, ensure the Max Heart Rate field is empty.
Updating Max Heart Rate:
- On the ErgZone app
- Go to "Settings" (gear icon on the top left of the ErgZone app)
- Scroll to the Heart Rate section and provide your MAX Heart Rate.
- Remove the MAX Heart Rate data.
Hide the HR column
Don't use a Heart Rate monitor during a workout? No problem.
You can hide the HR information. Here is how:
- On the ErgZone app
- Go to Settings (gear icon on the top left of the ErgZone app)
- Scroll to the Heart Rate section
- Toggle Display Heart Rate
Projected Finish Time(*)
A projected finish time is available for workouts where all intervals/splits are for distance (meters).
Press the “Time” column twice during the workout to see it.

*This metric is available for ErgZone Groups owner/premium members only and on workouts where all intervals/splits are for distance (meters).
