Hi, I have an outdoor ride from last year in which I held 339W for 20 mins and 346W for 8 mins. After that ride, TR automatically calculated my FTP at 307W, but I have no idea how it got to that. 95% of 339W is 322W and 90% of 346W is 311W. Does anyone have any idea why the discrepancy?
No, but the typical definition of an FTP is not what you can hold for 20 mins x .95 as a ‘20 minute’ testing protocol typically requires an anaerobic strain ahead of the 20 minute steady state to ensure you are using the right ‘systems’ for the test, i.e. aerobic.
Does TR detect new FTP from outside rides and other workouts? I didn’t know that. Only ever had a new FTP proposed from doing the ramp test.
It does not.
It certainly seems to be calculating my FTP for me. I started using TR a month ago but my FTP history is complete all the way back to before I even owned a power meter - all I have done is import my rides from Strava and it has produced that screenshot. I didn’t even own a power meter in 2014 so why on earth would I have entered 199W.
Going forward TR will not do that. Pulling in past rides as a newcomer TR does grab other FTP tests and the like. Not sure of the exact metrics behind pulling in past Strava rides. I do recall it did something similar for me when I started in July 2018.
OK thanks for the info
