Getting Your VO2 Max. Estimate for Running

This feature requires a heart rate monitor.

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.

  1. Run for at least 10 minutes outdoors.
  2. After your run, select Save.
  3. Select Menu > My Stats > VO2 Max..
