How to Estimate Your FTP
20-Minute Test (Gold Standard): Warm up 10–15 min, then ride as hard as possible for 20 min. Take 95% of average power as FTP.
Ramp Test: Use a smart trainer app (Zwift, TrainerRoad) — follow ramp protocol until failure.
Field Test: Hill climb or flat time trial — use best-effort sustained power for 20–60 min.
