FTP stands for Functional Threshold Power, which is commonly defined as the highest average power you can sustain for an hour, measured in watts.

Think of power at VO2max as your upper limit of aerobic energy production and FTP as the percentage of that limit that you can sustain.

When looking at the variables that determine endurance performance—VO2, FTP and efficiency—FTP is the variable that is both easily measured and trainable.

Setting a benchmark FTP will enable you to establish training zones so you can best distribute your training time and work toward improvement.
