10K Pace Calculator
Turn a 10K target into a pace per kilometre and per mile, and the time to be on at each split.

The formula
pace = target time ÷ 10 km
The splits assume an even pace from start to finish. Each one is the elapsed time to be on when you pass that point.
What to watch out for
The first half of a 10K should feel controlled. If you can talk in short sentences at 2 km, that is about right. The race gets hard from around 6 km, and the aim is to hold pace there rather than to speed up early.
Check your time at 5 km against the table. If you are more than about 30 seconds ahead, ease off slightly: that time often does not survive the last 3 km.

What is the halfway time for a 50-minute 10K?
25:00 at an even pace. Being a few seconds outside that is fine if you feel strong.
How much slower is 10K pace than 5K pace?
Typically by a few per cent. On the Riegel estimate, a 25:00 5K runner does 10K at 5:13 per km.
