Cycling Power Zones Calculator

Calculates personalized training power zones for cyclists based on their functional threshold power (FTP). The tool accepts a user's FTP number and then generates specific workout ranges using several established cycling models, including Coggan, Polarized, Sweet Spot, and British Cycling methodologies. Users input their core metric, and the calculator outputs structured intensity zones that define target effort levels for different types of training sessions. Athletes who follow structured endurance training or are interested in optimizing their performance benefit from this resource. Coaches use it to assign scientifically backed workouts, while dedicated cyclists rely on it to ensure they train within appropriate physiological boundaries.
