Getting Your FTP Estimate

The device uses your user profile information from the initial setup to estimate your functional threshold power (FTP). For a more accurate FTP value, you can conduct an FTP test using a paired power meter and heart rate monitor (Conducting an FTP Test).

Select > My Stats > Power > FTP.

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 have a paired power meter and heart rate monitor (Pairing Your Wireless Sensors).

  1. Select > My Stats > Power > FTP > > FTP Test > Ride.
  2. Press to start the activity timer.

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

  1. Press to stop the activity timer.
  2. Select Save.

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

Automatically Calculating FTP

Before the device can calculate your functional threshold power (FTP), you must have a paired power meter and heart rate monitor (Pairing Your Wireless Sensors).

NOTE: The estimate may seem inaccurate at first. The device requires a few rides to learn about your cycling performance.

  1. Select > My Stats > Power > FTP > > Auto Detect FTP.
  2. Ride at a steady, high intensity for at least 20 minutes outdoors.
  3. After your ride, select Save.
  4. Select > My Stats > Power > FTP.

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