FTP Tips
FTP (Functional Threshold Power) is your sustainable power for 60 minutes
Quick Facts
Pro cyclists produce 6+ W/kg. Recreational riders produce 2-3 W/kg
Note
Measure power with a power meter for accuracy. Estimates are available online
How Power-to-Weight Ratio Works
Power-to-weight ratio is your sustained power output divided by body weight.
- Calculation: Power (watts) รท Body Weight (kg)
- Critical for climbing and sustained efforts
- Professional cyclists: 6+ W/kg
- Advanced amateurs: 4-5 W/kg
- Recreational: 2-3 W/kg

Power-to-Weight FAQ
How do I measure power output?
Use a power meter on your bike (crank, hub, or pedal-based). Trainer and online calculators can estimate it.
Can I improve my power-to-weight ratio?
Yes! Both increasing power (training) and losing weight help. A 5% weight loss and 5% power gain is significant.
Is peak power the same as FTP?
No. Peak power is maximum for seconds; FTP is sustainable for 60 minutes. FTP is more useful.
