⚡ Performance & Training Calculators

FTP zones, calories burned, speed/distance/time, power-to-weight, VO2max, hill climb, wind resistance, and TSS calculators.

Calculate your seven power training zones based on Functional Threshold Power (FTP). Used by coaches worldwide for structured training.

Estimate calories burned during cycling based on weight, speed, duration, and terrain. Accounts for wind resistance and gradient.

Calculate any one of speed, distance, or time given the other two. Essential for planning rides and setting training targets.

Calculate your power-to-weight ratio (W/kg) and see how you compare to different cycling categories from beginner to pro.

Estimate your VO2max from cycling power data or a field test. Compare your aerobic capacity against age and gender benchmarks.

Estimate your climbing time based on power, weight, gradient, and distance. Compare against KOM/QOM benchmarks for popular climbs.

Calculate how wind affects your cycling speed. See the power cost of headwinds and the free speed from tailwinds at any power output.

Calculate Training Stress Score for rides using power or heart rate data. Track training load to optimize fitness and avoid overtraining.
