Hello. I know I am suppose to calibrate my wheel on trainer, every time, 10-15 minutes into the ride, blah blah blah… but I never do (dumb move #1). Then, for no apparent reason, I calibrated it before my latest ramp test while the trainer was still ice-cold (dumb move #2). I got a spin down value of 15 seconds. Then I took my ramp test and improved my FTP by 4.5%, or 11 watts, which was 2 watts higher than my all time high earlier in the year, before I got injured and had to take some time off. I do feel fitter, and I was expecting an increase, but now I can’t shake the notion that I cooked the books by calibrating right before my test.
This evening, I did my first hard over-under workout with the new FTP. I calibrated again before starting the workout, because now I am paranoid. Got a spin down of 15 seconds again. As expected, the workout was very hard, but I did finish it without turning down the intensity or backpedaling. Then, out of curiosity, I calibrated at the end of the workout and got a spin down of 19 seconds. I figure I’ll just leave it there since that value was recorded when the trainer was warm.
So did my FTP actually increase, or am I calibration-doping? Also, what is calibration anyway? If I use a power meter and power match while training indoors, isn’t my power just being recorded from my power meter? Shouldn’t the power from my power meter be legit (which I do calibrate every time!) regardless of what I do (or fail to do) with my trainer?
