Complete Cycling Calculator Suite 2026
Professional cycling calculators for power training, gearing optimization, and performance analysis. Train smarter with tools trusted by cyclists, triathletes, and coaches worldwide.
Power Training Calculators
FTP Calculator
Calculate Functional Threshold Power using 20-minute, 8-minute, or ramp test protocols. Set power zones for training.
Power-to-Weight Calculator
Calculate watts per kilogram for climbing performance. Compare to cycling categories and competitive standards.
Watts to Calories Calculator
Convert power output to energy expenditure. Plan nutrition and hydration for long rides and races.
Cycling HR Zones
Calculate heart rate zones specifically for cycling. Correlate with power zones for comprehensive training.
Power Zone Calculator
Calculate 7 power zones from your FTP. Includes zone descriptions and training recommendations for each level.
Cycling VO2 Max
Calculate VO2 max from cycling power data and performance. Cycling-specific aerobic capacity assessment.
The gear these numbers assume
Every pace, zone and power figure on this page assumes something is measuring it. These are the three that cover running, cycling and the threshold work in between.
Garmin Forerunner 965
Multisport with the training-load and threshold metrics most of these calculations assume you can actually see day to day.
