Pace = time ÷ distance. Finish time = pace × distance. Distance = time ÷ pace. Presets set both distance and its matching unit; results assume even pacing and do not predict race performance.

How this tool works
Pace, speed, distance, and elapsed time are derived from distance ÷ time and its rearranged forms, with unit conversion applied before the result is displayed.
Limits to know
Distance must be positive and elapsed time must use the displayed unit. Stops, elevation, course accuracy, GPS error, and changing pace are not modeled; the result is an average.
