FTP CALCULATOR BY AGE & GENDER

Estimate where your W/kg sits among trained amateur masters cyclists in the same age group and gender cohort.

This tool estimates an age-graded benchmark; it does not set training zones. For seven power ranges, use the general FTP calculator.

Age groups: 40-44, 45-49, 50-54, 55-59, 60+. Under 40? Try the open W/kg calculator.

MOVE UP A BAND

Coaching built around how masters cyclists actually adapt.

Polarised volume, sharper intensity, strength that protects, and recovery treated as a session. 7-day free trial. $195/month.

METHODOLOGY

Formula: W/kg = FTP (watts) ÷ body weight (kg). FTP should be determined from a 20-minute all-out test (×0.95) or ramp test, not estimated.

Cohort model: The percentile bands are heuristic distributions of trained amateur masters cyclists by gender and five-year age group (40-44, 45-49, 50-54, 55-59, 60+). Built from Coggan power profiling adjusted for amateur (non-professional) populations and the masters decline observed across published age-graded results. Treat as directional — the goal is a fair sense of where you sit among trained masters peers, not a federation ranking.

Limitations: W/kg predicts climbing speed but not flat-terrain performance (where absolute watts matter more). Body weight should be measured consistently (morning, before eating). FTP accuracy is the biggest variable in the result — if your last test was over three months ago, retest first.
