Ftp From Test
A precise tool.
What is the Ftp From Test & How does it work?
Functional Threshold Power (FTP) represents the highest average power you can sustain for approximately one hour of effort, making it a cornerstone metric for cyclists and triathletes.
The most common method to estimate FTP is the 20‑minute test, where you record your average power over a 20‑minute all‑out effort and multiply by a 0.95 conversion factor to approximate the one‑hour value.
Knowing your FTP helps you set training zones, gauge progress, and plan race strategies. It can also be expressed relative to body weight for a more nuanced performance insight.
FTP = P_{avg} times 0.95
P_{avg} = average power during test (W)

Frequently Asked Questions
What is FTP in sports?
FTP stands for Functional Threshold Power, which is the highest average power you can sustain for about one hour of continuous effort.
How do I calculate my FTP using this calculator?
Enter your average power from a 20-minute all-out effort, and multiply it by 0.95 to estimate your one-hour FTP.
Why is FTP important for cyclists?
FTP helps cyclists set training zones, gauge fitness levels, and plan race strategies effectively.
Can I use this calculator for triathletes too?
Yes, FTP is also crucial for triathletes as it aids in overall performance and pacing during races.
What does the 0.95 conversion factor represent?
The 0.95 factor converts your 20-minute average power to an estimated one-hour sustainable power.
How often should I test my FTP?
It’s recommended to retest your FTP every 4-6 weeks or after significant changes in training intensity.
Can this calculator be used for indoor cycling too?
Yes, the same principles apply whether you’re riding outdoors or on an indoor trainer.
