A functional threshold power (FTP) assessment in cycling measures the highest average power a rider can maintain for one hour. Online tools and software applications designed for this purpose estimate this crucial performance metric based on shorter, maximal efforts, such as a 20-minute time trial. These resources then apply a standardized formula to predict the one-hour sustainable power, providing cyclists with a personalized FTP value.
Knowing one’s FTP allows for structured training based on power zones, optimizing workouts for specific physiological adaptations, from improving endurance to boosting sprint capabilities. This data-driven approach replaces guesswork with precision, enabling athletes to track progress, tailor training plans, and ultimately reach their performance goals more effectively. While laboratory testing offers the most accurate FTP assessment, these digital tools provide a convenient and accessible alternative for cyclists of all levels.
