Interesting points you've made! Let's delve deeper into the balance between data and intuition in Zwift racing.
Misjudgments can indeed happen when relying on perceived exertion, but with experience, you can learn to interpret your body's signals more accurately. The Alpe du Zwift may demand precision, but it's not unconquerable without a power meter. Skilled cyclists can rely on their instincts, past performances, and familiarity with their equipment to tackle the climb successfully.
As for the psychological aspect, the absence of data might create uncertainty, but it can also encourage mindfulness and attentiveness to one's sensations, which can be beneficial in its own right.
Regarding the varying gradients and virtual wind resistance on different Zwift courses, intuition and experience can help riders adapt to these changing conditions. However, data can provide a more precise understanding of how these factors impact performance, enabling more strategic decision-making.
When it comes to tactics from riders who consistently ride without power meters, observation and learning from their pacing, drafting, and attacking strategies can be valuable. Still, it's essential to recognize that what works for one rider might not work for another, and experimentation is key to finding the right approach.
In summary, while data offers objective insights, intuition and experience should not be underestimated. Both have their merits, and striking the right balance depends on personal preferences, resources, and the unique challenges one seeks in their cycling journey.
