Intensity Factor® (IF)

Use Intensity Factor to easily see how hard was a ride compared to your overall fitness. It is calculated as a ratio of the workout's Normalized Power and your Functional Threshold Power.

For example, an intensity of 100% represents a ride with a Normalized Power equivalent to your FTP.
