Pace Calculator
Find your running pace in minutes per kilometer from any race or training run. Enter your total time and distance to instantly see how fast you ran each kilometer.
About this calculator
Running pace is the time it takes to cover one unit of distance, expressed in minutes per kilometer (or per mile). The formula converts your total elapsed time into seconds, divides by distance, then converts back to minutes: pace (min/km) = (hours × 3600 + minutes × 60 + seconds) / distance / 60. For example, a 5 km run in 25 minutes yields a pace of 5:00 min/km. Pace is the inverse of speed — a lower number means faster running. Knowing your pace helps you set even effort across a run, target race finishing times, and structure interval training sessions with precision.
How to use
Suppose you ran 10 km in 0 hours, 52 minutes, and 30 seconds. Convert total time to seconds: (0 × 3600) + (52 × 60) + 30 = 3,150 seconds. Divide by distance: 3,150 / 10 = 315 seconds per km. Divide by 60: 315 / 60 = 5.25 minutes per km, which equals a pace of 5:15 min/km. Enter 10 in Distance, 0 in Hours, 52 in Minutes, and 30 in Seconds to get the same result instantly.
Frequently asked questions
How do I calculate my running pace per kilometer from a race time?
Divide your total race time in seconds by the distance in kilometers, then divide again by 60 to get minutes per kilometer. For example, finishing a 10 km race in 50 minutes gives (50 × 60) / 10 / 60 = 5:00 min/km. This pace calculator automates all those conversions for you. Knowing your race pace helps you plan future training runs and set realistic time goals.
What is a good running pace for a beginner runner?
For most beginner runners, a comfortable pace falls between 7:00 and 9:00 min/km (about 11–14 min/mile). The right pace is one where you can hold a conversation without gasping — often called the 'talk test.' As fitness improves over weeks of consistent training, your comfortable pace will naturally decrease. Focus on effort and consistency first; speed follows with time.
What is the difference between running pace and running speed?
Pace is expressed as time per unit of distance (e.g., 5:30 min/km), while speed is expressed as distance per unit of time (e.g., 10.9 km/h). They are mathematical inverses: speed (km/h) = 60 / pace (min/km). Runners typically use pace because it directly maps to race strategies — you know exactly how long each kilometer should take. Cyclists and swimmers more commonly reference speed.
