page 15 ), and set your maximum heart rate ( Setting Your Heart
Rate Zones , page 11 ).
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.
2
After your ride, select Save Ride .

Select Menu > My Stats > VO2 Max. .
Your VO2 max. estimate appears as a number and position

Tips for Cycling VO2 Max. Estimates
The success and accuracy of the VO2 max. calculation
improves when your ride is a sustained and moderately hard
effort, and where heart rate and power are not highly variable.
• Before your ride, check that your device, heart rate monitor,
and power meter are functioning properly, paired, and have
good battery life.
• During your 20 minute ride, maintain your heart rate at
greater than 70% of your maximum heart rate.
• During your 20 minute ride, maintain a fairly constant power
output.
• Avoid rolling terrain.
• Avoid riding in groups where there is a lot of drafting.
Setting Your Heart Rate Zones
The device uses your user profile information from the initial
setup to determine your heart rate zones. You can manually
adjust the heart rate zones according to your fitness goals
( Fitness Goals , page 11 ). For the most accurate calorie data
during your activity, you should set your maximum heart rate,
resting heart rate, and heart rate zones.
1
Select Menu > My Stats > Training Zones > Heart Rate
Zones .
2
Enter your maximum and resting heart rate values.
The zone values update automatically, but you can also edit
each value manually.
3
Select Based On: .
4 Select an option:
• Select
BPM to view and edit the zones in beats per
minute.
• Select % Max. to view and edit the zones as a percentage
of your maximum heart rate.
• Select % HRR to view and edit the zones as a percentage
of your resting heart rate.
About Heart Rate Zones
Many athletes use heart rate zones to measure and increase
their cardiovascular strength and improve their level of fitness. A
heart rate zone is a set range of heartbeats per minute. The five
commonly accepted heart rate zones are numbered from 1 to 5
according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
Fitness Goals
Knowing your heart rate zones can help you measure and
improve your fitness by understanding and applying these
principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve
cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table
( Heart Rate Zone Calculations , page 22 ) to determine the best
heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the
calculators available on the Internet. Some gyms and health
centers can provide a test that measures maximum heart rate.
The default maximum heart rate is 220 minus your age.
Tips for Erratic Heart Rate Data
If the heart rate data is erratic or does not appear, you can try
these tips.
• Reapply water to the electrodes and contact patches (if
applicable).
• Tighten the strap on your chest.
• Warm up for 5 to 10 minutes.
• Follow the care instructions (
Caring for the Heart Rate
Monitor , page 18 ).
• Wear a cotton shirt or thoroughly wet both sides of the strap.
Synthetic fabrics that rub or flap against the heart rate
monitor can create static electricity that interferes with heart
rate signals.
• Move away from sources that can interfere with your heart
rate monitor.
Sources of interference may include strong electromagnetic
fields, some 2.4 GHz wireless sensors, high-voltage power
lines, electric motors, ovens, microwave ovens, 2.4 GHz
cordless phones, and wireless LAN access points.
Installing the Speed Sensor
NOTE: If you do not have this sensor, you can skip this task.
TIP: Garmin recommends you secure your bike on a stand while
