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 70
). If you are
using a chest heart rate monitor, you must put it on and pair it with your device.
For the most accurate estimate, complete the user profile setup (
Setting Up Your User Profile, page 23
) and set
your maximum heart rate (
Setting Your Heart Rate Zones, page 24
). 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.
Turning Off VO2 Max. Recording

Viewing Your Fitness Age
Your fitness age gives you an idea of how your fitness compares with a person of the same gender. Your
device uses information, such as your age, body mass index (BMI), resting heart rate data, and vigorous activity
history to provide a fitness age. If you have a Garmin Index
™
scale, your device uses the body fat percentage
metric instead of BMI to determine your fitness age. Exercise and lifestyle changes can impact your fitness
age.
NOTE: For the most accurate fitness age, complete the user profile setup (
).
1 From the Garmin Connect app, select
or
.
2 Select Health Stats > Fitness Age.
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.
