## What is Run Pace Calculator & Splits?

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.

PRIVACY
Everything runs on your device. No account, no sign-up, no ads, and nothing about your training is uploaded.

FULL ACCESS
The pace calculator is free to use. Unlocking Pro adds the race finish predictor, the split-time planner, and unlimited saved history — available as a weekly or yearly subscription, or a one-time lifetime purchase. Manage or cancel anytime in your App Store settings.

Punch in your numbers and get your pace right now.
