don’t worry about FTP. You’re repeatability at the efforts will improve which is much more important for improving. FTP is not the only metric that matters, but Time To Exhaustion and FRC (ability to do work above FTP) are now in play, and they are all inter-related…one goes up, other goes down, etc.
FTP is important, but I’d focus on the weekly races and learning how to race. You can do an FTP workout 1x a week if you like, and that will help you build your aerobic engine, but then ride some solid endurance miles on the weekend, and that will help you improve as well.
Would be awesome to hear how the season progresses; keep up posted on this thread if you can!
