Pace Calculator

Enter two values and get the third: pace from distance and time, finish time from distance and pace, or distance from time and pace.

Times at this pace

How long you would take at exactly this pace. Over longer distances you slow down, though – for a 50:00 10K, the race predictor forecasts a marathon of about 3:50:01.

What is running pace?

Pace is how long it takes you to cover one mile – for example 9:00 per mile. Runners prefer pace to speed because it lines up directly with the watch: at a 9:00 pace, every mile takes nine minutes.

How to calculate your pace

Divide your time by the distance:

Pace = Time ÷ Distance

Example: a half marathon (13.1 miles) in 2:05:00 works out to 9:32 per mile. The other way round, time = pace × distance and distance = time ÷ pace – that's exactly what the calculator above does, depending on which value you're after.

Converting pace and speed

To turn pace into speed, divide 60 by your pace in minutes: a 10:00 mile is 60 ÷ 10 = 6 mph. For odd values and the treadmill, use the pace converter with its ready-made chart.

Prefer kilometers? Switch the unit at the top of the page to km – every calculator then shows min/km and km/h.

FAQ

What does pace mean in running?

Pace is the time you need for one mile (or one kilometer), e.g. 10:00 per mile. The lower the number, the faster you are.

How do I calculate my pace?

Divide your running time by the distance. 3 miles in 27 minutes gives 27 ÷ 3 = 9 minutes – a 9:00 pace per mile.

Can I use my pace to predict another distance?

Only roughly. At the same pace, time = pace × distance – but you slow down over longer races. So a 50:00 10K doesn't mean a 3:30:59 marathon, more like 3:50:01. For a realistic estimate, use the race predictor.

How fast should I run in training?

Most runs should be much slower than race pace – slow enough to hold a conversation. The training pace calculator gives you personal paces for easy runs, threshold and intervals.

Can I print my splits?

Yes. “Print” gives you a clean list of the result and splits, and “Copy link” lets you share your calculation. For a compact pace band with race strategy and fueling, use the split calculator.
