Getting Your VO2 Max. Estimate for Running
This feature requires wrist-based heart rate or a
compatible chest heart rate monitor. If you are using a
chest heart rate monitor, you must put it on and pair it with
your watch (
Pairing Your Wireless Sensors, page 58
).
For the most accurate estimate, complete the user profile
setup (
Setting Up Your User Profile, page 67
), and set
your maximum heart rate (
Setting Your Heart Rate Zones,
). The estimate may seem inaccurate at first. The
watch requires a few runs to learn about your running
performance. You can disable VO2 max. recording for
ultra run and trail run activities if you do not want those
run types to affect your VO2 max. estimate (
).
1 Start a running activity.
2 Run for at least 10 minutes outdoors.
3 After your run, select Save.
4 Press UP or DOWN to scroll through the performance
measurements.
Getting Your VO2 Max. Estimate for Cycling
This feature requires a power meter and wrist-based
heart rate or a compatible chest heart rate monitor. The
power meter must be paired with your watch (
). If you are using a chest heart
rate monitor, you must put it on and pair it with your
watch.
For the most accurate estimate, complete the user profile
setup (
Setting Up Your User Profile, page 67
) and set
your maximum heart rate (
Setting Your Heart Rate Zones,
). The estimate may seem inaccurate at first.
The watch requires a few rides to learn about your cycling
performance.
1 Start a cycling activity.
2 Ride at a steady, high intensity for at least 20 minutes.
3 After your ride, select Save.
4 Press UP or DOWN to scroll through the performance
measurements.
Viewing Your Predicted Race Times
For the most accurate estimate, complete the user profile
setup (
Setting Up Your User Profile, page 67
), and set
your maximum heart rate (
Setting Your Heart Rate Zones,
).
Your watch uses the VO2 max. estimate and your training
history to provide a target race time (
). The watch analyzes several weeks of
your training data to refine the race time estimates.
1 From the watch face, press UP or DOWN to view the
performance glance.
2 Press START to view glance details.
3 Press UP or DOWN to view a predicted race time.
4 Press START to view predictions for other distances.
NOTE: The predictions may seem inaccurate at first.
The watch requires a few runs to learn about your
running performance.
Heart Rate Variability Status
Your watch analyzes your wrist heart rate readings while
you are sleeping to determine your heart rate variability
(HRV). Training, physical activity, sleep, nutrition, and
healthy habits all impact your heart rate variability. HRV
values can vary widely based on gender, age, and fitness
level. A balanced HRV status may indicate positive signs
of health such as good training and recovery balance,
greater cardiovascular fitness, and resilience to stress.
An unbalanced or poor status may be a sign of fatigue,
greater recovery needs, or increased stress. For best
results, you should wear the watch while sleeping. The
watch requires three weeks of consistent sleep data to
display your heart rate variability status.
