So Trainerroad has the Ramp Test to estimate your FTP. Your best minute's power on the ramp is considered your MAP, Maximum Aerobic Power, and the app assumes that your FTP is 75% of your MAP. So here's the thing. If MAP is equivalent to VO2max, then I do know that VO2max is not particularly easy to increase with training, assuming you're already a fairly well-trained cyclist. So if I've pretty much hit the ceiling on my Vo2 max, how can I increase my FTP? First thing that occurs to me is that 75% relationship between FTP and MAP can possibly change, but is that it? Is that the only way I can increase my FTP?
