6:45 marathon pace
| Per mile | 15:27 |
|---|---|
| Per km | 9:36 |
| Halfway | 3:22:30 |
| Speed | 6.3 km/h |
A 6:45:00 marathon averages 15:27 per mile or 9:36 per kilometre — 6.3 km/h (3.9 mph) — held for all 26.2 miles (42.195 km). It is a run-walk or steady finish that sits inside the time limit at many big-city marathons, though not all of them — check your race's cut-off.
Run evenly, you reach halfway in 3:22:30. On a flat course that is the target: a first half a shade slower costs very little, while banking time early is the most reliable way to lose it, and more, in the last 10 km.
Riegel's race-prediction formula puts the equivalent half marathon at 3:11:34, the 10K at 1:25:32 and the 5K at 40:28. Treat those as the minimum rather than the target: the formula assumes marathon-specific endurance, and runners on lower weekly mileage — first-timers especially — usually need to be faster over the shorter distances to hold this pace for the full marathon.
These are even splits for a flat course. On a hilly one the same finish time needs a different target for every kilometre, which the course pages grade-adjust from each marathon's own elevation profile.

Frequently asked questions
What pace is a 6:45 marathon?
15:27 per mile, or 9:36 per kilometre, for the full 26.2 miles. That is 6.3 km/h or 3.9 mph.
What is the halfway split for a 6:45 marathon?
3:22:30 at even pace. On a flat course, arriving a little later than that is safer than arriving early; on a hilly course the right halfway time depends on where the climbing sits.
What half marathon time do I need for a 6:45 marathon?
Riegel's formula says 3:11:34 (9:05/km). Most runners need to be somewhat quicker than that — the prediction assumes you have the long-run endurance to hold pace for twice the distance, and it is optimistic for runners on modest weekly mileage.
What 5K and 10K times match a 6:45 marathon?
About 40:28 for 5K and 1:25:32 for 10K by the same formula. Shorter races are a weaker guide to the marathon than a half is, because they depend much less on endurance.
Is 6:45 a good marathon time?
It is a run-walk or steady finish that sits inside the time limit at many big-city marathons, though not all of them — check your race's cut-off. Whether it is the right goal for you depends on your recent race results and training, not on where it sits in the field.
