Calculator
Pace calculator.
Enter a pace for a distance and see the projected finish time, equivalent times at other distances, and the easy and tempo ranges that follow from it. Everything is an estimate for planning – not a prediction.
Equivalent times use the Riegel formula (exponent 1.06) from your entered performance. They are estimates for planning, not predictions.
Enter a pace and distance to see the finish time, equivalent times and training pace ranges.
How to use it
- Use a recent effort – a race or a hard time trial – for the most realistic numbers.
- Check your training against the easy range. If your normal runs are faster than it, you are probably running your easy days too hard.
- Switch between km and mi at the top of the page; the numbers convert automatically.
