Calculator
Race time converter.
Enter a recent race result and see what it suggests for other distances, plus the easy and tempo pace ranges that follow. Useful for setting realistic targets before a training block.
Equivalent times use the Riegel formula (exponent 1.06) from your entered performance. They are estimates for planning, not predictions.
Enter a recent race result to see equivalent times at other distances.
Reading the results
- Longer-distance equivalents assume you have trained for the distance. A fast 5K does not automatically mean a fast marathon.
- The formula is more accurate between nearby distances and less accurate across big jumps.
- Use the ranges as targets, then adjust for how training actually goes.
