So I decided I would do an outdoor FTP test since I was riding on a paved trail and I could do it with no interruptions. I did the test and my "outdoor" FTP was 40 points higher than my Trainerroad FTP. So then I tried to continue my ride with 65%-75% of my new FTP and again I could not stay in the range, my watch was always beeping at me that my power was too high or too low. I tried really hard on focusing on riding with the same force and efficiency and but I could not stay in that range.
So what do I do? Is this a growing pain of learning to ride with power? Should my outdoor FTP be that much different from my Trainerroad FTP? I will say I still get good workouts on trainerroad. Any help or suggestions appreciated.
