How to Calculate Running Pace

Running pace is your time per unit of distance — usually expressed as min/km or min/mile. To calculate it, divide your total finishing time by the distance. For example, if you ran a half marathon (21.1 km) in 1 hour 45 minutes, your pace is 105 ÷ 21.1 = 4:59 min/km (8:01 min/mile).

How to Convert Pace to Speed

To convert pace (min/km) to speed (km/h), divide 60 by your pace. For example, 5:00 min/km = 60 ÷ 5 = 12.0 km/h. For mph, divide 60 by your min/mile pace — a 8:00 min/mile pace = 60 ÷ 8 = 7.5 mph. This calculator shows both pace and speed automatically.
