You probably realize that ‘threshold’ is an important measure for endurance athletes. But there seem to be many different types of thresholds measures out there, and that might be confusing for some. In this episode, the panel explores the many types of thresholds (e.g. FTP, critical power, lactate threshold): how they are determined, whether they are the same or different, whether they are interchangeable, how they relate to each other, and what it all means for the real-world coach and cyclist.
