Run Pace Calculator & Splits vs Running Memo

Need your running pace in seconds? Enter any two of pace, time, or distance and PaceCalc instantly solves the third — in kilometers or miles, with speed shown in both km/h and mph. No guessing, no spreadsheet math. Most pace tools stop at one number. PaceCalc goes further: it forecasts every race distance from a single result, builds a segment-by-segment split plan for race day, and keeps a history of every calculation you save — so the number you need is always one tap away. WHAT YOU GET - Instant pace, time, or distance from the other two, in km or miles - Speed readout in km/h and mph on every result - Race finish predictions from 1K to 100K ultra using the proven Riegel model - Even, negative, and positive split tables for any distance - A saved history of your calculations to revisit and compare - Built-in coaching articles on pacing, splits, and training zones PERFECT FOR - 5K and 10K runners chasing a personal best - Half and full marathon racers planning goal pace - Treadmill and track athletes dialing in tempo and intervals - Coaches setting split targets for their runners WHY NOT JUST USE A GENERIC CALCULATOR? A phone calculator gives you one division. PaceCalc understands running: it converts pace between km and miles correctly, predicts your finish across every distance, and lays out the exact splits to hit your goal — something a stopwatch and a notepad can't do in one place.
