I was riding outside with a mate yesterday morning. We have approximately the same level, we are in the 1st group of our road cycling club, yet our ftp is completely different, mine is around 170 watts his around 285 watts. By the way our weight is similar… We don’t have the same equipment, I have an old Bkool smart pro and he has a Kickr Core. I just discovered there are many issues of power calibration with Bkool smart trainers. How can I make my FTP more accurate on TrainerRoad, knowing I have an FTP Ramp test in two days.
