How can you be certain youve hit a plateau in Zone 2 gains when the only metric most of you are tracking is your arbitrary, feel-based perception of effort. Zone 2 is supposed to be a quantifiable, data-driven zone, but most of you are still relying on your gut to tell you whether youre improving or not.
What is the actual, scientifically-backed method for determining when youve plateaued in Zone 2. Is it based on a specific number of weeks or months of training at a certain intensity, or is it based on a specific percentage increase or decrease in power output or heart rate.
How can you account for the inevitable variability in your training data, especially when youre training outdoors where conditions can change significantly from one ride to the next. And what about the impact of other factors like nutrition, sleep, and stress on your performance in Zone 2.
Are any of you actually using data to inform your training decisions, or are you just winging it and hoping for the best. And if you are using data, what specific metrics are you tracking and how are you using them to adjust your training.
It seems to me that most of you are just throwing around buzzwords like Zone 2 and FTP without actually understanding what they mean or how to apply them in a practical way. So lets get real for a minute and talk about the actual science behind training in Zone 2.
