10 Mile Pace Calculator
The 10 Mile is 16.1 km (10 miles · 16.09 km). At an even 5:00 /km (8:03 /mile) it takes 1:20:28 — 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.

10 Mile race-time predictions (Riegel estimate)
If your 10 Mile is worth 1:20:28, the Riegel formula estimates these equivalent times at other distances. These are estimates — real results depend on training, terrain and pacing.

How 10 Mile pace is calculated
Pace is simply time ÷ distance. This page works it out exactly: it converts your 10 Mile 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 10 Mile time?
"Good" depends entirely on the runner, but a useful reference point is even pacing. At 5:00 /km (8:03 /mile) a 10 Mile takes 1:20:28. 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 10 Mile?
A 10 Mile is 16.1 km, which is 10 miles (16.09 km). A mile is exactly 1609.344 m, so the conversion is exact rather than rounded.
What pace do I need for a 1:20:28 10 Mile?
To finish a 10 Mile in 1:20:28 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 10 Mile 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.
