Is the conventional approach to building cycling endurance, which emphasizes gradual and consistent progress, actually hindering our potential for rapid and significant gains? By sticking to traditional methods of periodized training, are we inadvertently limiting our ability to push beyond perceived physiological boundaries and achieve true breakthroughs in performance? Or is the emphasis on steady, incremental progress simply a reflection of the inherent risks and uncertainties associated with more aggressive and experimental training methods? What role should risk-taking and experimentation play in the pursuit of cycling endurance, and at what point do the potential rewards outweigh the potential costs?
