Calculator
Pick a distance and enter a goal time. We’ll compute pace per km and per mile.

Important pacing note
A calculator gives you a starting pace target. It does not know whether the day is hot, windy, hilly, crowded, under-fueled, or ambitious for your current fitness. If the calculated pace looks right on paper but feels like threshold effort too early in training, re-check the goal with goal-time guidance, race-based prediction, or sub-threshold pace estimates.
Key checkpoints (marathon)
When distance is set to marathon, we show common markers: 5k, 10k, half, 30k, 40k and finish.
Printable pace band
Best option: generate a wrist pace band or A4 pacing sheet, then print or save as PDF.
Tip: use the calculator above to pick your goal time, then open the PDF pace band (wrist or A4).
Downloadable templates (sub-X pace bands)
If you want a quick “ready-to-share” template page, use these. Each is a shortcut for a common marathon goal.
If your club has a standard goal time, link the matching template. If not, link the generator with your exact time.
Full 1 km splits (optional)
If you want a detailed table, open this. It can be long for a marathon.

Tip: if your goal time isn’t listed, the calculator still works—goal pages are just shortcuts for common targets.
Methodology and intended use
This calculator uses straightforward finish-time math: total goal time divided by selected race distance, then converted into pace-per-kilometre, pace-per-mile, and key cumulative checkpoints.
What this tool is good for
Use it to set a clean pacing framework, generate checkpoints, build a pace band, compare common goal times, and pressure-test whether your target makes sense in the context of recent race performances and workouts.
It works especially well alongside: marathon pace workouts, training-plan structure, threshold support for marathon training, and conditions-based pacing adjustments.
What this tool does not know
It does not know your injury status, recovery capacity, fueling plan, heat adaptation, course profile, or whether your goal is realistic. That is why the best workflow is: estimate pace here, validate it with training and race data, then adjust when real-world conditions demand it.
Marathon pace calculator FAQ
How do I calculate pace per mile from pace per km?
Multiply pace-per-km seconds by 1.609344 to get pace per mile, or use this calculator.
Should I aim for even splits?
Most runners do best with steady pacing and a controlled first half. Small negative splits can happen naturally if you stay calm early.
What should I do if conditions are hot or hilly?
Use effort as the guide. Expect slower splits in heat or hills and focus on consistency rather than forcing exact numbers.
Is marathon pace the same as threshold pace?
No. Marathon pace is slower and more sustainable than threshold pace. If you want a better feel for that difference, read tempo vs threshold vs marathon pace or use the sub-threshold pace calculator.
