How to update iLevels on Garmin Edge 1000 and Edge 520 (WKO4)

Garmin Edge 1000 and Edge 520 devices (though currently not the 520 Plus) can use WKO4 individual power levels (iLevels), the newest metric for cyclists and triathletes who train with a power meter. Dr. Andrew Coggan developed the iLevels to be based on each athlete’s unique physiology and current level of fitness.

To set up your Garmin 520/1000 to utilize Coggan iLevels:

  1. Make sure you're using the latest firmware for your device. If you're using an Edge 1000, you'll need 7.4 or newer; if you're using an Edge 520, you'll need 5.24 or newer.
  2. Set the zones on your Garmin device to Coggan iLevels.
  • Select Menu > My Stats > Training Zones > Power Zones> Based On > watts
  • Select Menu > My Stats > Training Zones > Power Zones> Configuration > 9 Coggan iLevels
  • Your FTP will be automatically set to your sFTP in WKO4 when you sync your Garmin with WKO4.

To sync your device with WKO4:

  1. Open WKO4 on your computer.
  2. Plug in your Garmin device.
  3. Wait for your device to be recognized and ASSOCIATE YOUR GARMIN DEVICE WITH THE SELECTED ATHLETE. Please note, if you do not associate the device with the athlete, the auto-updating of FTP and iLevels will not function.

At the end of the syncing process, you will see a notification in WKO4 confirming that your iLevels have been updated on your Garmin device.



  1. If you change FTP settings or add files while the Garmin unit is plugged into WKO4, changes will not be recognized until the next time you sync the Garmin.
