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 Forerunner device (
Pairing Your Wireless Sensors, page 77
). If you are
using a chest heart rate monitor, you must put it on and pair it with your device. If your Forerunner 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 24
) and set
your maximum heart rate (
Setting Your Heart Rate Zones, page 25
). 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.
2 After your ride, select Save.
3 Select UP or DOWN to scroll through the performance measurements.
TIP: You can select START to view additional information.
Heat and Altitude Performance Acclimation
Environmental factors such as high temperature and altitude impact your training and performance. For
example, high altitude training can have a positive impact on your fitness, but you may notice a temporary VO2
max. decline while exposed to high altitudes. Your Forerunner device provides acclimation notifications and
corrections to your VO2 max. estimate and training status when the temperature is above 22ºC (72ºF) and
when the altitude is above 800 m (2625 ft.). You can keep track of your heat and altitude acclimation in the
training status widget.
NOTE: The heat acclimation feature is available only for GPS activities and requires weather data from your
connected smartphone.
Viewing Your Predicted Race Times
For the most accurate estimate, complete the user profile setup (
Setting Up Your User Profile, page 24
), and set
your maximum heart rate (
Setting Your Heart Rate Zones, page 25
).
Your device uses the VO2 max. estimate (
About VO2 Max. Estimates, page 41
) and your training history to
provide a target race time. The device analyzes several weeks of your training data to refine the race time
estimates.
TIP: If you have more than one Garmin device, you can enable the Physio TrueUp
™
feature, which allows your
device to sync activities, history, and data from other devices (
Syncing Activities and Performance
).
1 From the watch face, select UP or DOWN to view the performance widget.
2 Select START to scroll through the performance measurements.
Your projected race times appear for 5K, 10K, half marathon, and marathon distances.
NOTE: The projections may seem inaccurate at first. The device requires a few runs to learn about your
running performance.
