Normalized Power® (NP) is a power averaging method, measured in watts, used to compensate for changes in ride conditions for a more accurate depiction of power expenditure.

Conventional power measurement is based off of a steady resistance. Riding on a bike trainer or stationary cycle provides a steady resistance allowing conventional methods to give you an accurate power reading. However, riding outdoors produces changes in resistance (e.g., changes in elevation, terrain, or wind). NP® takes into account the changing resistances to provide more accurate power output data.

The purpose this serves is directly related to your training. NP® takes into account your body's reaction to change in exercise intensity due to changing resistance. This allows for a more accurate representation of your power output which in turn allows you to train within more realistic power confines. This gives way to a more productive training session.

Devices that will show Normalized Power®:

  • Edge 500/510/520
  • Edge 800/810
  • Edge 1000
  • epix
  • fenix 2/3
  • Forerunner 910XT/920XT
  • quatix 3
  • tactix Bravo

If NP® is not an optional data field, update the software using Garmin Express.

You will find NP® in Garmin Connect on the activity's details page. There will be a Power section within the Details box.
