What pace do I need for a 25:00 5K?

A 25:00 5K is 5:00/km (8:03/mi), 12.0 km/h, held for the whole race.

What treadmill speed is 25:00 5K pace?

Set the treadmill to 12.0 km/h or 7.5 mph to run 5:00/km (8:03/mi).

Where should I be at halfway in a 25:00 5K?

With even pacing you pass halfway in 12:30; with a negative split, a little later.

What does a 25:00 5K predict for other distances?

The Riegel formula estimates 52:07 for the 10K, 1:26:19 for the 10-mile race, 1:55:00 for the half marathon, 3:59:47 for the marathon, assuming you’ve trained for each distance.

Sub-25 5K pace (25:00)

A 25-minute (sub-25) 5K is 5:00/km (8:03/mi), 12.0 km/h.

What a 25:00 5K predicts

Estimate

Estimated times at other distances (Riegel formula)
Distance	Estimated time
10K	52:07
10 miles	1:26:19
Half marathon	1:55:00
Marathon	3:59:47

These are estimates from the Riegel formula, T2 = T1 × (D2 ÷ D1)^1.06. They assume you’ve trained for the other distance, so treat them as a guide, not a promise.

From 20 to 25 minutes, the first kilometre sets it up

Start on goal pace, not faster. The first kilometre of a 5K feels easier than it is.

Two or three runs a week, one with short fast efforts, and a regular timed 5K will move you through this band.

Use the ladder to pick a target: in this band, 30 seconds off your 5K is only a few seconds per km.
