Use the Power Curve Calculator to calculate your fitness signature and corresponding power curve based upon best-efforts that you have performed from fresh to failure. For example, if you recently performed a 20 minute FTP Test at 250W, fill in 250 for the Power value and 1200 for the Duration value. If you have performed additional tests or have other best effort data from recent activities, enter additional power-duration values. The Xert calculator works best with 3 best-effort power-duration values but will also estimate your fitness and power-duration curve with two or even just one set of values.
