Whats the point of periodizing zone 2 training throughout the year, especially for road cyclists who seem to be more concerned with their wattage output than actual physical conditioning? Doesnt the monotony of grinding out endless miles at a moderate intensity negate any potential benefits of periodization?
Are the incremental gains in cardiovascular fitness and muscular endurance really worth the risk of stagnation and overtraining that can come with a rigid periodization plan? And what about the arbitrary nature of defining different training zones - isnt this just a way for coaches and self-proclaimed experts to justify their own existence and sell overpriced training plans to gullible cyclists?
Isnt it more effective to simply focus on building overall fitness and resilience through a mix of high-intensity interval training, strength work, and long, slow distance rides, rather than getting bogged down in the minutiae of periodization? Or is this just a cop-out for those who cant handle the structure and discipline required to periodize their training effectively?
