Three Calculation Modes
Pace → Time: Know your training pace and want to know your projected finish time for 5K, 10K, half marathon, or marathon. Enter your min/km or min/mile and see all race times instantly.
Time → Pace: Have a goal finish time and need to know what pace to run. Enter your goal time and distance and get the required pace per km and per mile.
Speed → Pace: Your treadmill or bike computer shows km/h or mph. Enter the speed to get your equivalent running pace.

How to Calculate Running Pace
Pace = Total Time ÷ Distance. If you run 10km in 50 minutes: 50 ÷ 10 = 5:00 per kilometer. To get the pace in seconds: (50 × 60) ÷ 10 = 300 seconds = 5:00/km. To convert to miles: multiply by 1.60934. So 5:00/km = 8:03/mile.
Frequently Asked Questions
What is the difference between pace and speed?
Pace measures time per distance (min/km or min/mile). Speed measures distance per time (km/h or mph). They are inverses: Pace (min/km) = 60 ÷ Speed (km/h).
How do I calculate my running pace?
Divide your total time (in minutes) by the distance in kilometers. For example, 45 minutes for 8km = 45 ÷ 8 = 5:37 per kilometer.
What is a 5:00/km pace in mph?
5:00 per kilometer equals 12 km/h, which is 7.46 mph.
How do I convert min/km to min/mile?
Multiply your min/km pace by 1.60934. So 5:00/km × 1.60934 = 8:03/mile.
