5K Pace Calculator
The 5K is 5 km (3.11 miles · 3.11 miles). At an even 5:00 /km (8:03 /mile) it takes 25:00 — that is 12 km/h (7.46 mph). Enter your own target time below.
Pace and speed are derived from one exact figure — your speed in metres per second — so min/km, min/mile, km/h and mph all agree and round-trip exactly. 1 mile = 1609.344 m.
Note: The most-run race distance in the world — a 5K is exactly 5 km, about 3.107 miles.

5K race-time predictions (Riegel estimate)
If your 5K is worth 25:00, the Riegel formula estimates these equivalent times at other distances. These are estimates — real results depend on training, terrain and pacing.
| Distance | Predicted | Pace /km | Pace /mile |
|---|---|---|---|
| 1500 m | 6:59 | 4:39 | 7:29 |
| 3000 m | 14:33 | 4:51 | 7:48 |
| 1 Mile | 7:31 | 4:40 | 7:31 |
| 10K | 52:07 | 5:13 | 8:23 |
| 15K | 1:20:07 | 5:20 | 8:36 |
| 10 Mile | 1:26:19 | 5:22 | 8:38 |

| 100 Mile | 16:31:01 | 6:09 | 9:55 |
How 5K pace is calculated
Pace is simply time ÷ distance. This page works it out exactly: it converts your 5K into metres and your time into seconds, divides to get one speed in metres per second, then expresses that single number as min/km, min/mile, km/h and mph. Because a kilometre is exactly 1000 m and a mile exactly 1609.344 m, the four figures always agree and convert back to machine precision. Only the Riegel predictions above are estimates.
FAQ
What is a good 5K time?
"Good" depends entirely on the runner, but a useful reference point is even pacing. At 5:00 /km (8:03 /mile) a 5K takes 25:00. Enter your own target above and the calculator shows the exact pace and speed you need; the pace chart below lists finish times for every pace from 3:00 to 8:00 /km.
How many kilometres is a 5K?
A 5K is 5 km, which is 3.11 miles (3.11 miles). A mile is exactly 1609.344 m, so the conversion is exact rather than rounded.
What pace do I need for a 25:00 5K?
To finish a 5K in 25:00 you hold 5:00 per kilometre, which is 8:03 per mile, or 12 km/h (7.46 mph). The split table below shows the clock at every kilometre and mile for that pace.
How are the 5K race-time predictions calculated?
They use the Riegel formula, t₂ = t₁ × (d₂ / d₁)^1.06, a published 1977 model that scales a known result to another distance. It is an estimate, not a guarantee — real times depend on training, terrain, heat and pacing — and it is the only estimate on this page. Every pace and speed conversion here is exact.
