Operation Manual

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.
Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try these
tips.
• Make sure you have the HRM-Run accessory.
Accessories with running dynamics have on the front of the
module.
• Pair the HRM-Run accessory with your fēnix
3 device again,
according to the instructions.
• If the running dynamics data display shows only zeros, make
sure the heart rate monitor is worn right-side up.
NOTE:
Ground contact time and balance appears only while
running. It is not calculated while walking.
Physiological Measurements
These physiological measurements require a compatible heart
rate monitor. The measurements are estimates that can help
you track and understand your training activities and race
performances. These estimates are provided and supported by
Firstbeat
.
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 published data sources to provide a target race time
based on your current state of fitness. This projection also
presumes you have completed the proper training for the
race.
Recovery advisor: The recovery advisor displays how much
time remains before you are fully recovered and ready for the
next hard workout.
Stress score: Stress score measures 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.
Lactate threshold
: Lactate threshold is the point where your
muscles start to rapidly fatigue. Your device measures your
lactate threshold level using heart rate and pace.
About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you
can consume per minute per kilogram of body weight at your
maximum performance. In simple terms, VO2 max. is an
indication of athletic performance and should increase as your
level of fitness improves. The fēnix 3 device has separate VO2
max. estimates for running and cycling. You can use your
Garmin device paired with a compatible heart rate monitor and
power meter to display your cycling VO2 max. estimate. You
can use your Garmin
device paired with a compatible heart rate
monitor to display your running VO2 max. estimate.
Your VO2 max. estimate appears as a number and position on
the color gauge.

Getting Your VO2 Max. Estimate for Running
Before you can view your VO2 max. estimate, you must put on
the heart rate monitor and pair it with your device (Pairing ANT+
Sensors
, page
20). If your fēnix
3 device was packaged with a
heart rate monitor, the devices are already paired. For the most
accurate estimate, complete the user profile setup (
Setting Up
Your User Profile, page 9)
, and set your maximum heart rate
(
Setting Your Heart Rate Zones, page 9).
NOTE: The estimate may seem inaccurate at first. The device
requires a few runs to learn about your running performance.
1
Run for at least 10 minutes outdoors.
2
After your run, select
Save.
3
Hold

Getting Your VO2 Max. Estimate for Cycling
Before you can view your VO2 max. estimate, you must put on
the heart rate monitor, install the power meter, and pair them
with your fēnix
3 device (

your fēnix
3 device was packaged with a heart rate monitor, the
devices are already paired. For the most accurate estimate,
complete the user profile setup (

and set your maximum heart rate (
Setting Your Heart
Rate Zones,

.
NOTE:
The estimate may seem inaccurate at first. The device
requires a few rides to learn about your cycling performance.
1
Ride at a steady, high intensity for at least 20 minutes
outdoors.

After your ride, select
Save.

Viewing Your Predicted Race Times
This feature requires a heart rate monitor.
For the most accurate estimate, complete the user profile setup
