What pace per kilometre and what speed a 25:00 5K actually is. Straight division, no prediction.

A 5K in 25:00 is a round mark and the maths has no trick: time divided by five kilometres. The pace above is what you have to hold on average, not the cheerful first kilometre.
Starting 15 seconds faster than this example is the usual way to arrive cooked at kilometre four. If the goal is to break 25, run this pace on controlled efforts and put the faster work in the intervals, not the other way around.
How this was calculated
Pace = total time / kilometres. There is no training formula here: it is the arithmetic of a result you already have.
Nearby values
The same calculation changing only the time. The highlighted row is this example.
| Time | Result | |
|---|---|---|
| 23:00 | 4:36 min/km | 13.0 km/h |
| 24:00 | 4:48 min/km | 12.5 km/h |
| 25:00 | 5:00 min/km | 12.0 km/h |
| 26:00 | 5:12 min/km | 11.5 km/h |
| 27:00 | 5:24 min/km | 11.1 km/h |

The Riegel formula assumes adequate training for the target distance. For marathons it tends to overestimate.

Frequently asked questions
What pace do you need to run 5K in 25 minutes?+
A 5 km in 25:00 is 5:00 min/km (12.0 km/h). It is the average of the whole race. A faster first kilometre is not a cushion.
What is that in km/h?+
A 5 km in 25:00 is 5:00 min/km (12.0 km/h). Speed sits next to the pace. On a treadmill, set that speed. The treadmill does not ask for minutes per kilometre.
