I find ramp tests mentally fatiguing and throws my week’s training schedule into chaos. How do you deal with that?Ramp tests are also less demanding physically and so can be done with one or two days rest, though I didn't do any for mine (Still it's relative and my level of freshness should be similar if I perform each test in the same way.)
In the beginning of the season, testing every four weeks is not granular enough. For example, I have added about 16 W back (295 W —> 309 W) in just two weeks of training. (In the past, my guessed FTP increases have been backed up by subsequent FTP tests, I’m usually right within a watt or two.)
Uff, you are quite hard on yourself I don’t know whether Zwift’s test is identical to TrainerRoad’s, but at 19:30 you are testing equal to your current FTP. Adding one minute on top of that adds a significant chunk to your FTP.The only aim is to hold on for 1 minute longer than last time.
