It is advised to do a Ramp FTP test before completing ZA. My FTP was at 225Watts. I completed the ZA and was happy when I completed.
I had 3 days rest before I did another FTP test, and did the long version of the 20minutes. I finished with a new FTP 208.
For some reason I lost 17Watts. Gutted is not the word how I feel.
Anyway, if anyone shed some light on this subject please do?
