Cycling calculators

Cycling is a highly quantified sport where performance is measured in speed, cadence, and power. Functional Threshold Power (FTP) and power-to-weight ratios are the standard metrics for cycling fitness, determining how fast a rider can climb or sustain efforts. In cycling, average speed is a simple measure of performance, but it is heavily affected by terrain, wind, and drafting. For training, power output is the most reliable metric because it is unaffected by environmental factors. Functional Threshold Power (FTP) estimates the maximum wattage a rider can sustain for an hour, serving as the basis for power zones. On climbs, power-to-weight ratio (watts per kilogram) is the critical predictor of climbing speed. Gear ratios and cadence calculations help riders optimize their pedaling efficiency. Our cycling calculators automate the calculations for FTP zones, power-to-weight ratios, and average speeds, giving you the numbers you need to structure your training.
