performance condition feature to avoid some of these notifications. 1 From the watch face, hold . 2 Select Settings > Physiological Metrics > Performance Condition. Detecting Performance Measurements Automatically The Auto Detect feature is turned on by default. The device can automatically detect your maximum heart rate and lactate threshold during an activity. When paired with a compatible power meter, the device can automatically detect your functional threshold power (FTP) during an activity. NOTE: The device detects a maximum heart rate only when your heart rate is higher than the value set in your user profile. 1 Hold . 2 Select Physiological Metrics > Auto Detect. 3 Select an option. Syncing Activities and Performance Measurements You can sync activities, personal records, and performance measurements from other Garmin devices to your Forerunner device using your Garmin Connect account. This allows your device to more accurately reflect your training status and fitness. For example, you can record a ride with an Edge device, and view your activity details and overall training load on your Forerunner device. 1 From the watch face, hold . 2 Select Settings > Physiological Metrics > TrueUp. When you sync your device with your smartphone, recent activities, personal records, and performance measurements from your other Garmin devices appear on your Forerunner device. About VO2 Max. Estimates VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body weight at your maximum performance. In simple terms, VO2 max. is an indication of athletic performance and should increase as your level of fitness improves. The Forerunner device requires wristbased heart rate or a compatible chest heart rate monitor to display your VO2 max. estimate. The device has separate VO2 max. estimates for running and cycling. You must run either outside with GPS or ride with a compatible power meter at a moderate level of intensity for several minutes to get an accurate VO2 max. estimate. On the device, your VO2 max. estimate appears as a number, description, and position on the color gauge. On your Garmin Connect account, you can view additional details about your VO2 max. estimate, including your fitness age. Your fitness age gives you an idea of how your fitness compares with a person of the same gender and different age. As you exercise, your fitness age can decrease over time. Purple Blue Green Orange Red Superior Excellent Good Fair Poor VO2 max. data is provided by FirstBeat. VO2 max. analysis is provided with permission from The Cooper Institute®. For more information, see the appendix (VO2 Max. Standard Ratings, page 44), and go to www.CooperInstitute.org. 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 device (Pairing Your Wireless Sensors, page 29). 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 8), and set your maximum heart rate (Setting Your Heart Rate Zones, page 8). The estimate may seem inaccurate at first. The device requires a few runs to learn about your running performance. 1 Run for at least 10 minutes outdoors. 2 After your run, select Save. 3 Select START 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 Forerunner device (Pairing Your Wireless Sensors, page 29). 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 8) and set your maximum heart rate (Setting Your Heart Rate Zones, page 8). 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 START to scroll through the performance measurements. 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. Full acclimation takes a minimum of 4 training days. Viewing Your Predicted Race Times For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page 8), and set your maximum heart rate (Setting Your Heart Rate Zones, page 8). Your device uses the VO2 max. estimate (About VO2 Max. Estimates, page 15) 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 Measurements, page 15).
