Your FTP Doesn't Matter. This Does

🚴 FREE 6-Week Training Plan - raise your FTP and build the engine to hold it, on just 4 hours a week. Includes ready-to-ride Zwift workouts: https://cyclingnutshell.kit.com/freeplan Is FTP really the best way to measure a cyclist, or is durability the number that actually decides races? This one runs on published sports science and pro peloton power data, not group-ride bragging. In this video we break down why your FTP is only half the story: what FTP actually measures and why the classic 20-minute test tends to overestimate your true threshold and hour power, why every one of those numbers is taken fresh on rested legs, what durability is and why it may matter more than FTP, the capacity versus access idea where a huge engine behind a blocked fuel line gets you nowhere late in a race, the pro research showing fresh power barely separates the best riders from the rest while power under fatigue does, why your lactate threshold and the top of zone 2 drift downward as you tire, how training age explains the gap between a flying junior and a seasoned pro, why there's no standard durability test and how to build your own repeatable protocol, and how to train it for real with years of volume and zone 2, polarized training, fatigued-state intervals, strength work in the gym, and modern high-carb fueling of 90 to 120 grams an hour.
