Functional Threshold Power
20-minute test without correction factor (60-minute test)
The Testing Procedure
20-minute test without correction factor (60-minute test)
20-minute test (according to the Allen-Coggan protocol):
- Complete warm-up (including short high-intensity efforts to pre-fatigue the system).
- 20-minute maximal test, pedaling at the maximum sustainable and constant effort from start to finish.
- Calculation: take 95% of the average power (Watts) recorded during the 20-minute effort:
60-minute test
By definition, FTP is the power you can sustain for approximately one hour.
- How it works: you pedal at the highest possible constant intensity for 60 consecutive minutes.
- Calculation: FTP corresponds to the exact average power recorded during the hour of effort (without any percentage reduction).
- Disadvantages: extremely difficult to manage from a mental perspective and in terms of pacing. It is nearly impossible to find a stretch of open road without interruptions, descents, or intersections for a solid hour.
