Buyer's guide

How to choose a pace calculator

When picking a pace calculator, first decide whether you are training for a specific race distance or doing general fitness work. If you have a target race like a 5K or marathon, a tool with preset events will save you time converting miles to kilometers or hours to minutes. If you are doing custom workouts, interval training, or need to mix units like yards and meters, look for a calculator that lets you input any two of the three variables without forcing you into a preset distance.

Questions

Pace Calculator FAQ

How do I convert my marathon pace to a per-mile pace?
Enter the marathon distance and your target finish time into the calculator; it will output your average pace per mile automatically, and most tools also show how that pace compares to typical finishing times for your experience level.
Can I use a pace calculator for walking or biking, not just running?
Yes, many pace calculators accept any activity type and will compute pace per mile or per kilometer regardless of whether you are running, walking, or biking, as long as you input the total distance and time.
What if I only know my pace and time; how do I find the distance I covered?
Input your pace (time per mile or kilometer) and total time spent moving; the calculator will multiply the two to give you the total distance, which you can then compare to your target race length.
Do I need to enter time in a specific format like hh:mm:ss?
Most calculators accept flexible time entries; you can often type just minutes and seconds (e.g., 5:3) without leading zeros, but check the tool's instructions to be sure.
