Run Pace Calculator - PaceCalc

PaceCalc is the pace calculator runners actually want to open. Pick any distance, set a goal time, get the exact pace and full split schedule — then export a card worth posting. One tool. Three modes. Pick two, get the third. • PACE mode — Set distance and target time to get your per-km or per-mile pace. • TIME mode — Set distance and target pace to calculate your finish time. • DISTANCE mode — Set time and pace to calculate how far you’ll go.
