Sub-threshold ride
What it means
Intensity Factor (IF) is simply your ride's normalized power divided by your FTP. An IF of 1.0 means you averaged right at threshold; 0.7 is a steady endurance ride; above 1.0 means you spent significant time over threshold.
IF lets you compare how hard two rides were regardless of length — a quick, honest read on intensity.
