Use this free online pace calculator to find your running or walking pace and speed from any distance and time. Enter your distance, choose kilometers or miles, and enter the hours, minutes, and seconds it took to cover that distance to instantly see your pace per unit and overall speed.
How to Use the Pace Calculator
Enter your Distance covered.
Choose the Distance Unit - Kilometers or Miles.
Enter the Time Taken in Hours, Minutes, and Seconds.
Click "Calculate Pace" to see your pace and speed.
Pace and Speed Formulas
Pace and speed describe the same effort from opposite directions. Pace is how long one kilometre (or mile) takes; speed is how far you go in one hour. Runners usually think in pace because it is easy to check against a watch at each kilometre marker.
Pace = total time in seconds ÷ distance. The calculator then splits this into whole minutes and seconds, rounding to the nearest second.
Speed = distance ÷ time in hours, shown to one decimal place in km/h or mph.
To switch between them: speed in km/h = 60 ÷ pace in minutes per km. A 6:00 min/km pace is 10 km/h; a 5:00 pace is 12 km/h.
Worked Examples
A 10 km run in 55 minutes: 3,300 seconds ÷ 10 = 330 seconds, which is 5 minutes 30 seconds per km. Speed is 10 ÷ (55 ÷ 60) = 10.9 km/h.
A 5 km race in 28:45: 1,725 seconds ÷ 5 = 345 seconds, or 5:45 min/km, at 10.4 km/h.
A 4 km morning walk in 45 minutes works out to 11:15 min/km, or 5.3 km/h, which is a typical brisk walking speed.
A half marathon (21.0975 km) in exactly 2 hours: 7,200 ÷ 21.0975 = 341.3 seconds, displayed as 5:41 min/km and 10.5 km/h. Enter the full race distance, not a rounded 21 km, or the pace will come out slightly slow.

Holding an even pace for the whole race gives these finish times (hours:minutes:seconds). The half marathon is 21.0975 km and the full marathon 42.195 km.

Using Your Pace in Training and Races
Plan a target race pace: enter the race distance and your goal time to get the pace to hold at every kilometre marker.
Start slightly slower than goal pace. Going out too fast in the first few kilometres is the most common reason runners fade in the second half. Finishing the second half a little faster than the first, called a negative split, is usually the more efficient strategy.
Most easy runs should feel conversational, often a minute or more per km slower than your 10 km race pace. Building mileage at an easy pace develops endurance with less injury risk.
Expect to slow down in heat and humidity. In much of India, early morning runs are cooler, and pace on a hot, humid day is not a fair comparison with a cool one.
GPS watches and phone apps often record a little more distance than the certified course, because of weaving around other runners and signal drift in cities. Use the official race distance when checking a finish time.
Frequently Asked Questions
Pace is calculated by dividing your total time (converted to seconds) by the distance you entered, then converting the result to minutes and seconds per kilometer or mile.
Speed is calculated as distance divided by time in hours, and is shown in km/h if you chose kilometers or mph if you chose miles.
Yes. It works for any activity where you know the distance and the time taken, including walking, running and cycling. Cyclists usually prefer the speed figure, while runners and walkers tend to use pace per km.
One mile is 1.609 km, so multiply the pace per km by 1.609. A 6:00 min/km pace is about 9:39 per mile. Going the other way, divide a per-mile pace by 1.609. You can also enter the same run once in kilometres and once in miles (distance ÷ 1.609) to compare.
There is no fixed number. A good beginner pace is one at which you can still speak in full sentences, which for many new runners is somewhere around 7 to 9 minutes per km, and slower is fine. Walk-run intervals are a sensible way to build up. Consistency matters far more than speed in the first few months.
