I am currently preparing for the Evans Hill Climb. I am starting with the sweet spot part 2 followed by the Evans plan. TrainingPeaks has an article that says TSB should not go below -20 more than once every ten days. I am relatively new to training with a power meter but am confidant that my ftp is 200. However, as I build into the plan, my TSB keeps falling below -20 and occasionally falls below 30. I am fatigued on those days but still able to complete the training schedule. Do you suggest dialing back to stay above -20 or pushing through?
