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). If your fēnix® 5/5S 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), and set your maximum heart rate (Setting Your Heart Rate Zones). The estimate may seem inaccurate at first. The device requires a few runs to learn about your running performance.
