about your performance (Syncing Activities and Performance Measurements, page 15). 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. 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®.

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 22). 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 UP or DOWN to view the performance widget. 4 Select START to scroll through the performance measurements. Recovery Time You can use your Garmin device with wrist-based heart rate or a compatible chest heart rate monitor to display how much time remains before you are fully recovered and ready for the next hard workout. NOTE: The recovery time recommendation uses your VO2 max. estimate and may seem inaccurate at first. The device requires you to complete a few activities to learn about your performance. The recovery time appears immediately following an activity. The time counts down until it is optimal for you to attempt another hard workout. Viewing Your Recovery Time 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). 1 Go for a run. 2 After your run, select Save. The recovery time appears. The maximum time is 4 days. NOTE: From the watch face, you can select UP or DOWN to view the performance widget, and select START to scroll through the performance measurements to view your recovery time. Recovery Heart Rate If you are training with wrist-based heart rate or a compatible chest heart rate monitor, you can check your recovery heart rate value after each activity. Recovery heart rate is the difference between your exercising heart rate and your heart rate two minutes after the exercise has stopped. For example, after a typical training run, you stop the timer. Your heart rate is 140 bpm. After two minutes of no activity or cool down, your heart rate is 90 bpm. Your recovery heart rate is 50 bpm (140 minus 90). Some studies have linked recovery heart rate to cardiac health. Higher numbers generally indicate healthier hearts. TIP: For best results, you should stop moving for two minutes while the device calculates your recovery heart rate value. You can save or discard the activity after this value appears. Training Load Training load is a measurement of your training volume over the last seven days. It is the sum of your excess post-exercise oxygen consumption (EPOC) measurements for the last seven days. The gauge indicates whether your current load is low, high, or within the optimal range to maintain or improve your fitness level. The optimal range is determined based on your individual fitness level and training history. The range adjusts as your training time and intensity increase or decrease. 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 16) 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). 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. Performance Condition As you perform a running activity, 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 16 Heart Rate Features
