Cycling Speed Calculator

Calculate cycling speed, distance, or time. Includes pace, calorie burn estimates, and metric conversions.

Solve For controls which single output this calculator actually computes from the other inputs: solving for Speed divides Distance by the Hours-and-Minutes total, solving for Time divides Distance by the Speed you enter, and solving for Distance multiplies Speed by the time total instead. Only two of the distance/time/speed inputs are read at once — whichever variable Solve For targets is computed, not read from its own input field, so entering a value there has no effect until you switch modes. With the default Solve For Speed selected, Distance is the input that moves the primary Speed output the most, since Body Weight and the Speed field itself play no role in that calculation at all. Calories Burned is estimated from a standard MET (metabolic equivalent) table keyed to the computed speed band — faster riding uses a higher MET value — multiplied by Body Weight and the resulting duration (the MET figure is interpolated between the Compendium's published band values rather than stepped, so the estimate moves smoothly rather than jumping when your speed crosses a band edge). Body Weight always affects the calorie estimate regardless of which mode you're solving for, since calorie burn is calculated from the resolved Speed and Time no matter which one was the original input. This is a MET-table estimate, not a power-meter or heart-rate-based measurement, so it does not account for terrain, wind, drafting, or individual fitness level.
