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 77). 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 24) and set your maximum heart rate (Setting Your Heart Rate Zones, page 25). 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. 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. Viewing Your Predicted Race Times For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page 24), and set your maximum heart rate (Setting Your Heart Rate Zones, page 25). Your device uses the VO2 max. estimate (About VO2 Max. Estimates, page 41) 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 40). 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. 42 Heart Rate Features
