What is Functional Threshold Power?
Functional Threshold Power (FTP) represents your ability to sustain the highest possible power output over 45 to 60 minutes, depending on whether you’re a trained athlete or not. As a result 95% of the 20 minute average power is used to determine FTP.
Why measure FTP?
Regular assessments of your FTP give you an indication of whether you are improving your performance. Plus, FTP provides a good ‘benchmark’ on which to base cycling-specific training zones.
