Getting Your FTP Estimate

Before you can get your functional threshold power (FTP) estimate, you must pair a chest heart rate monitor and power meter with your watch (Pairing Your Wireless Sensors), and you must get your VO2 max. estimate (Getting Your VO2 Max. Estimate for Cycling).

The watch uses your user profile information from the initial setup and your VO2 max. estimate to estimate your FTP. The watch will automatically detect your FTP during rides at a steady, high intensity with heart rate and power.

  1. Press UP or DOWN to view the performance glance.
  2. Press START to view glance details.
  3. Press UP or DOWN to view your FTP estimate.

    Your FTP estimate appears as a value measured in watts per kilogram, your power output in watts, and a position on the color gauge.

Conducting an FTP Test

Before you can conduct a test to determine your functional threshold power (FTP), you must pair a chest heart rate monitor and a power meter with your device (Pairing Your Wireless Sensors), and you must get your VO2 max. estimate (Getting Your VO2 Max. Estimate for Cycling).

NOTE: The FTP test is a challenging workout that takes about 30 minutes to complete. Choose a practical and mostly flat route that allows you to ride at a steadily increasing effort, similar to a time trial.
  1. From the watch face, select START.
  2. Select a cycling activity.
  3. Hold Menu symbol.
  4. Select Training > FTP Guided Test.
  5. Follow the on-screen instructions.

    After you begin your ride, the device displays each step duration, the target, and current power data. A message appears when the test is complete.

  6. After you complete the guided test, complete the cool down, stop the timer, and save the activity.

    Your FTP appears as a value measured in watts per kilogram, your power output in watts, and a position on the color gauge.

  7. Select an option:

    • Select Accept to save the new FTP.

    • Select Decline to keep your current FTP.
