Critical power (or rFTPw – threshold power) is the single-most important value to run and train with power effectively. This value tells the athlete how much power they can produce for a set time frame (that time frame varies by person) and the value can be scaled for any race duration. There are some differences between critical power and functional threshold power, but for now we will treat them as the same thing. There are several ways to estimate or determine your critical power.

What is Functional Threshold Power (FTP)?
Some insight and advice on CP/FTP testing. This article is for cycling with power, but it still largely applies to testing in general, not only for cycling.
Methods for estimating CP:
- 3/9 test
- 30-minute time trial
- 3/6 lap test
- Mean-maximal power curve
- Recent race result – using The Secret of Running table OR Stryd Powercenter.
