All calculations use 42.195 km and 1 mile = 1.609344 km. Chart paces are rounded to whole seconds; they are references, not exact inputs for reconstructing a finish time. Sub-4 has its own guide.

Use elapsed time at course markers to check your plan at 10K, halfway, 30K and 40K.
How is marathon pace calculated?
Divide your finish time by the marathon distance of 42.195 km. For a four-hour marathon:
A checkpoint time is your total finish time multiplied by the fraction of the course covered. At even pace, halfway through a four-hour marathon is exactly two hours.
The calculator keeps the full precision for splits, then rounds displayed elapsed times to the nearest second. Segment times are differences between those rounded checkpoints, so they add up to the displayed finish time.
Use the chart on race day
- Choose a goal supported by recent racing and training. The numbers describe a pace, not a fitness prediction.
- Compare your elapsed time with official course markers. Include stops; auto-pause can hide time that still counts in the race.
- Let effort guide you when the course or conditions change. Avoid chasing every fluctuation in instant GPS pace.
Marathon pace FAQ
What the chart means, where rounding matters, and how to take your splits with you.
What pace do I need for a four-hour marathon?
Exactly four hours over 42.195 km averages approximately 5:41.27 per km or 9:09.23 per mile. The quick chart rounds this to 5:41/km. Use elapsed-time checkpoints to track your goal; multiplying a rounded pace back by the distance gives a slightly different finish time. View the four-hour marathon guide.
Is 5:41 per kilometre enough for sub-4?
Mathematically, exactly 5:41/km for 42.195 km gives approximately 3:59:48. That leaves only about 12 seconds, so a watch showing 5:41/km does not guarantee sub-4. Use the sub-4 checkpoints and official course markers, with stops included in elapsed time.
Can I calculate finish time from my pace?
Yes. Choose Pace → finish time, enter minutes and seconds per kilometre or mile, and select your distance. For example, 6:00/km over a marathon gives approximately 4:13:10. Switching from a time target to a displayed, rounded pace can change the result slightly.
Should every kilometre be exactly the same pace?
The calculator shows an even-pace reference. Hills, weather, congestion and aid stations can change individual splits. The pace adjustment tools explore conditions, and the pace-band generator also offers controlled-start and negative-split plans.
Can I print or save my marathon splits?
Select Make my pace band to carry your chosen marathon time into the generator. Print the band or choose Save as PDF in your browser’s print dialog, where available. You can also download a phone card there, or copy checkpoints and download a CSV from this calculator.
Does this work for a half marathon, 10K or 5K?
Yes. Change the calculator’s distance to half marathon (21.0975 km), 10 km or 5 km. The results and downloadable splits use your selected distance. The quick and full marathon charts, and the pace-band generator, remain specific to 42.195 km.
Built around the practical side of pacing.
