Cycling Power Duration Curve Calculator vs Cycling Power Output Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Cycling Power Duration Curve Calculator
Estimate the maximum sustainable power you can hold for any duration from a 1-minute sprint to a multi-hour ride, using your FTP and anaerobic capacity. Ideal for race pacing and structured training planning.
- Answers
- Sustainable Power (watts)
- Inputs
- Functional Threshold Power (FTP), Anaerobic Work Capacity, Target Duration, Current Fatigue Level
Cycling Power Output Calculator
Estimate the watts you must produce to ride at a given speed on any gradient. Use it when planning training targets, comparing climbs, or dialing in aerodynamic setups.
- Answers
- Power Output (watts)
- Inputs
- Total Weight (rider + bike), Speed, Gradient, Aerodynamic Drag, Rolling Resistance
