Critical Power Calculator

Use this calculator to determine your athlete’s Critical Power, Anaerobic Capacity (W’), and physiology - Aerobic, Anaerobic, or Balanced - using the three-point (short, medium, long) testing method.

Keep in mind that a Short Test is typically about 2-3 minutes in length, a Medium Test is about 4-6 minutes in length, and a Long Test is about 10-12 minutes in length.

Instructions:

Input the values from your athlete’s three tests into the appropriate fields, and press the “Calculate” button. VERY IMPORTANT: Time must be entered as seconds (example, 6 minutes = 360 seconds).
