What is Functional Threshold Power (FTP)?

Coach Rob explains what Functional Threshold Power (FTP) is, how it’s measured using a power meter, and what to do with your FTP number when you know it.

FTP is essentially the power, in watts, that you could reasonably sustain for an hour in a race situation. It enables the calculation of different power ‘zones’ to train in for different types of fitness.

Heart rate data can be used as a proxy for threshold power – it won’t give you the pin-point accuracy that a power meter will, but it’s better than nothing!

We are a big fan of power meters – yes – they are expensive (but getting cheaper every year) but in terms of ensuring accuracy and consistency in training, there’s no better investment in our opinion
