Can anyone explain to me why power training has become so gospel among serious cyclists, when the vast majority of us will never come close to competing at a level where a 1% increase in wattage actually matters? Is it just a case of amateur cyclists trying to emulate the pros, or is there actual science backing up the idea that training with power meters and obsessing over watts/kg is essential for improvement? And what about the argument that all this focus on power is sucking the fun out of cycling, turning what used to be a joyful, social activity into a solo, data-driven grind? Is the pursuit of power really worth sacrificing the camaraderie and enjoyment that comes with group rides and casual spinning? And whats the deal with all the pseudo-scientific nonsense being peddled by some of the power training evangelists out there - can someone please explain to me what Functional Threshold Power actually means, and why I should care about it?
