sport.cycling-ftp Calculator
Calculates Functional Threshold Power (FTP) — the maximum average watts a cyclist can sustain for one hour — from a 20-minute test result, and derives the five training zones from it. FTP is the single most important number for structured cycling training.
Inputs
Ftp
Reference formula or conversion factor shown for context.
Weight
Body or object weight. For health calculators, usually in kg or lbs.
Hours
Reference formula or conversion factor shown for context.
Target Ftp
Reference formula or conversion factor shown for context.
Results
W/kg
Reference formula or conversion factor shown for context.
target W/kg
Reference formula or conversion factor shown for context.
gap to target
The difference between the current value and the target. Positive gap means you are below target; negative means you have exceeded it.
level (male)
The measured or computed level on the applicable scale.
Z4 threshold range (W)
The difference between the maximum and minimum values.
training hours/week
The result expressed in hours. Divide by 24 to convert to days.
