Performance Condition
As you complete your activity, such as running or cycling, the performance condition feature analyzes your
pace, heart rate, and heart rate variability to make a real-time assessment of your ability to perform compared
to your average fitness level. It is approximately your real-time percentage deviation from your baseline VO2
max. estimate.
Performance condition values range from -20 to +20. After the first 6 to 20 minutes of your activity, the device
displays your performance condition score. For example, a score of +5 means that you are rested, fresh, and
capable of a good run or ride. You can add performance condition as a data field to one of your training
screens to monitor your ability throughout the activity. Performance condition can also be an indicator of
fatigue level, especially at the end of a long training run or ride.
NOTE: The device requires a few runs or rides with a heart rate monitor to get an accurate VO2 max. estimate
and learn about your running or riding ability (About VO2 Max. Estimates, page 42).
Viewing Your Performance Condition
This feature requires wrist-based heart rate or a compatible chest heart rate monitor.
1 Add Performance Condition to a data screen (Customizing the Data Screens, page 80).
2 Go for a run or ride.
After 6 to 20 minutes, your performance condition appears.
3 Scroll to the data screen to view your performance condition throughout the run or ride.
Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the
bloodstream. In running, it is the estimated level of effort or pace. When a runner exceeds the threshold, fatigue
starts to increase at an accelerating rate. For experienced runners, the threshold occurs at approximately 90%
of their maximum heart rate and between 10k and half-marathon race pace. For average runners, the lactate
threshold often occurs well below 90% of maximum heart rate. Knowing your lactate threshold can help you
determine how hard to train or when to push yourself during a race.
If you already know your lactate threshold heart rate value, you can enter it in your user profile settings (Setting
Your Heart Rate Zones, page 53).
Performing a Guided Test to Determine Your Lactate Threshold
This feature requires a Garmin chest heart rate monitor. Before you can perform the guided test, you must put
on a heart rate monitor and pair it with your device (Pairing Your Wireless Sensors, page 98).
The device uses your user profile information from the initial setup and your VO2 max. estimate to estimate
your lactate threshold. The device will automatically detect your lactate threshold during runs at a steady, high
intensity with heart rate.
TIP: The device requires a few runs with a chest heart rate monitor to get an accurate maximum heart rate
value and VO2 max. estimate. If you are having trouble getting a lactate threshold estimate, try manually
lowering your maximum heart rate value.
1 From the watch face, select .
2 Select an outdoor running activity.
GPS is required to complete the test.
3 Hold MENU.
4 Select Training > Lactate Threshold Guided Test.
5 Start the timer, and follow the on-screen instructions.
After you begin your run, the device displays each step duration, the target, and current heart rate data. A
message appears when the test is complete.
6 After you complete the guided test, stop the timer and save the activity.
If this is your first lactate threshold estimate, the device prompts you to update your heart rate zones based
on your lactate threshold heart rate. For each additional lactate threshold estimate, the device prompts you
to accept or decline the estimate.
