Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try
these tips.
y
Make sure you have a running dynamics accessory,
such as the HRM-Tri accessory.
Accessories with running dynamics have on the
front of the module.
y
Pair the running dynamics accessory with your
fēnix device again, according to the instructions.
y
If the running dynamics data display shows only
zeros, make sure the accessory is worn right-side
up.
NOTE:
Ground contact time and balance appears
only while running. It is not calculated while
walking.
Performance Measurements
These performance measurements are estimates
that can help you track and understand your training
activities and race performances. The measurements
require a few activities using wrist-based heart rate
or a compatible chest heart rate monitor. Cycling
performance measurements require a heart rate
monitor and a power meter.
These estimates are provided and supported by
Firstbeat. For more information, go to
.
NOTE:
The estimates may seem inaccurate at first.
The device requires you to complete a few activities to
learn about your performance.
VO2 max�:
VO2 max. is the maximum volume of
oxygen (in milliliters) you can consume per minute
per kilogram of body weight at your maximum
performance.
Predicted race times:
Your device uses the VO2 max.
estimate and your training history to provide a
target race time based on your current state of
fitness.
HRV stress test:
The heart rate variability (HRV) stress
test requires a Garmin chest heart rate monitor.
The device records your heart rate variability while
standing still for 3 minutes. It provides your overall
stress level. The scale is 1 to 100, and a lower
score indicates a lower stress level.
Performance condition:
Your performance condition
is a real- time assessment after 6 to 20 minutes of
activity. It can be added as a data field so you can
view your performance condition during the rest of
your activity. It compares your real-time condition
to your average fitness level.
Functional threshold power (FTP):
The device uses
your user profile information from the initial setup
to estimate your FTP. For a more accurate rating,
you can conduct a guided test.
Lactate threshold:
Lactate threshold requires a chest
heart rate monitor. Lactate threshold is the point
where your muscles start to rapidly fatigue. Your
device measures your lactate threshold level using
heart rate data and pace.
Turning Off Performance Notifications
Some performance notifications appear upon
completion of your activity. Some performance
notifications appear during an activity or when you
achieve a new performance measurement, such
as a new VO2 max. estimate. You can turn off the
performance condition feature to avoid some of these
notifications.

Detecting Performance Measurements
Automatically
The Auto Detection feature is turned on by default. The
device can automatically detect your maximum heart
rate and lactate threshold during an activity. When
runners tend to have quick and balanced strides.
You can watch the color gauge or data field during your run or view the summary on your Garmin Connect
account after your run. As with the other running dynamics data, ground contact time balance is a quantitative
measurement to help you learn about your running form.
Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and
whether it is positioned at the chest (HRM-Tri or HRM-Run™ accessories) or at the waist (Running Dynamics Pod
accessory).
