Using a power meter for hill repeats seems like the go-to approach for many cyclists looking to optimize their training, but is it really worth the investment for the average rider, or is it more of a gimmick reserved for the pros? On one hand, having real-time data on your power output can be incredibly useful for honing in on precise training zones and making adjustments on the fly. However, some argue that relying too heavily on power meters can lead to overthinking and a lack of instinctual riding skills. Others claim that the benefits of increased efficiency and accuracy in training far outweigh any potential drawbacks. What are your thoughts - do power meters offer a significant advantage for hill repeats, or can riders achieve similar results through other means, such as perceived exertion or heart rate monitoring?
