Functional Threshold Power, or FTP, is a serious stat talked about by many cyclists. The test can help you benchmark your performance, and understand how much power you’re able to exert as you cycle. Our expert guide will help you learn about Functional Threshold Power, and how to measure it.
Functional Threshold Power (FTP) represents your ability to sustain the highest possible power output over 60 minutes. The term doesn’t solely refer to outdoor riding, and can be calculated on indoor bike trainers too.
Why is FTP Important?
FTP is important for those cycling indoors because you can benchmark your ability and see how your training is affecting your performance.
If you are a beginner to indoor cycling who has never tested your FTP before, it provides a great benchmark on which to base your cycling specific training zones. Undertaking regular assessments will also give you a good indication of whether your performance is improving.

Your Functional Threshold Power is calculated from this 20 minutes, and your Functional Threshold Power score is measured in watts.
The FTP test is suitable for those with an exceptional level of fitness looking to understand their training zones and fitness in more detail. If you are a beginner to cycling testing, you should know that this is not a performance test to be taken lightly.
We recommend completing the test at the beginning and end of your training plan so you can see how your training has benefitted your fitness and cycling performance. The Functional Threshold Power test will take you 20 minutes of all-out effort cycling, so you need to be in suitable shape for the test to be an accurate reflection of your fitness.
3 Ways to Get the Most From Your FTP Test
In order for your Functional Threshold Power test to accurately assess your cycling performance, you need to be properly prepared. To see the benefits of indoor cycling you need to set realistic goals and prioritise your safety and health at all times. To see a real indication of your FTP, and complete the test properly, here are our top tips:
1. Come prepared
First things first, you’ll need to get your setup right. Be sure you are comfortable on your smart bike, choose your cycling sportswear wisely and get your indoor bike set up correctly, so you can give the test a maximal effort without worrying about any little irritations. If you are testing indoors, prep your space and ensure you have an indoor cycling fan, some hydration and a towel as you will sweat… a lot.
2. Get in condition
As the 20 minute test is a maximal effort, you’ll need to do a suitable indoor cycling warm up to prepare your body for the challenge. The Wattbike 20 minute warm up is a great option as it increases your muscle and core temperature, and offers an opportunity to mentally prepare for the performance test on the Wattbike Atom, all of which will improve your test performance.
3. Choose the right intensity
The 20 minute test is tough. You’ll need to quickly settle into an intensity which you feel you can sustain for the full 20 minutes, but also that allows you to exert yourself fully. The image below shows an even, well-paced 20 minute test:
