What Is the Functional Threshold Power Feature on My Garmin Device?

Functional Threshold Power (FTP) is a measurement from power meters. It is the highest power level you can maintain for one hour. FTP is beneficial because it provides an outlook on performance ability. Determining your FTP can be done through an FTP test using a compatible Garmin device.

How Is My FTP Estimate Determined by My Device?

Garmin devices take your user profile information from the initial setup to estimate your FTP. From there, once you have established a VO2 Max Estimate, that value will be used to determine your FTP Estimate.

For the most accurate value, you can conduct an FTP test using a paired power meter and heart rate monitor.

For instructions for performing an FTP test, refer to your owner's manual.

Why Am I Not Getting an Updated FTP Estimate Reading for My Recorded Activity?

NOTE: Activities recorded from third party sources will not update the FTP estimate on your Garmin Connect™ account.

In a guided FTP test, a new FTP estimate will only be generated if the following conditions are met:

• Activity must include heart rate data from either a built-in optical heart rate sensor or from a chest strap.

• 95% of the average power for a 20-minute interval within the ride must be greater than the current FTP setting.

• The average power for that interval of time must be greater than the previous 20-minute power record.

Outside of a guided FTP test, a new FTP estimate will only be generated if the following conditions are met:

• FTP Auto Calculation is enabled (refer to your owner's manual).

• Activity must include heart rate data from either a built-in optical heart rate sensor or from a chest strap.

• 95% of the average power for a 20-minute interval within the ride must be greater than the current FTP setting.

• The average power for that interval of time must be greater than the previous 20-minute power record.

Where Can I See My FTP Estimate in Garmin Connect Account?

Reports for previous FTP estimates are available in Garmin Connect account. These reports are updated when a new FTP estimate has been generated from a recorded activity and when you have made manual changes to your FTP setting. Manual changes to FTP may not appear in reports until you have recorded a cycling activity and synced your device.
