Critical Power Calculator
Critical power (CP) is the highest power you can sustain in a steady state, and it is one of the most useful numbers for setting training intensity and pacing. Enter two or three of your best maximal efforts below to estimate your CP and W′, the amount of work you can do above CP. CP isn't new, it was developed in the 1960/70 by Mayod sport scientist who characterised severe exercise in this manner. Its just re-surfaced recently.
How to test:
-
Do two or three all-out efforts on separate days, for example, 3 minutes and 12 minutes.
-
Pace each one evenly and ride it as hard as you can.
-
Enter the duration and average power for each effort.
