Can you establish your Critical Power (CP) by continuing effort past failure point of a Ramp Test for x number of minutes? This is on the basis that whatever effort I can sustain after emptying my ‘tank’ should be a good estimation of CP.
I’m trying to establish my Aerobic Work Capacity (W’), but need a CP value to do so accurately. My challenge is that I have no power meter on my outside workouts or during races as a MTB’r. Therefore, I have no reliable all-out efforts to establish CP - whilst I could use FTP as a basis for CP, I don’t want to assume that this is the same.
My ultimate goal is to be able to plot my potential power curve to see where my weaknesses are.
If this is not the best method, does anyone have any other recommendations? Oh, and I want to avoid deviating from my TR plan, so would rather not use a method that wipes me out!
