Running Pace Calculator

About this calculator

This calculator converts distance and time into running pace — minutes per kilometre and minutes per mile — plus your average speed. Pace is simply time ÷ distance, but runners think in pace rather than speed because it maps directly onto race splits: a 5:00/km pace means every kilometre should tick by in exactly five minutes if the effort stays even.

Runners and coaches use pace calculators constantly for race planning — converting a goal finish time (say, a sub-4-hour marathon) into the per-kilometre or per-mile splits needed to hit it, checking training run paces against target zones, and comparing performances across different race distances. Enter distance and time to get your pace and speed.
