Running Pace Calculator: Find Your Pace Per Mile or Km for 2026
Calculate your running pace, speed, and split times from distance and time. Supports both kilometers and miles.
How Running Pace Is Calculated
Running pace is the time it takes to cover one unit of distance, calculated by dividing total time by distance.
Split times assume even pacing throughout the run. Real-world splits typically show positive splits (slowing down) for recreational runners and negative splits (speeding up) for experienced racers.
How to Use the Running Pace Calculator
Enter your distance
Input the total distance run. Common race distances: 5K, 10K, half marathon (21.1 km / 13.1 mi), marathon (42.2 km / 26.2 mi).
Select distance unit
Choose between kilometers or miles based on your preference.
Enter your finish time
Input hours, minutes, and seconds for your total running time.
View your pace and splits
See your pace per km and per mile, speed in km/h and mph, and split times for each km or mile.
Real-World Scenario Example
"A runner completes a 5K race in 25 minutes and 0 seconds."
Inputs
Result
Pace of 5:00/km (8:03/mile), speed of 12.00 km/h (7.46 mph), with even 5:00 splits per kilometer.
Important Disclaimer
Pace calculations assume even effort distribution. Actual race performance varies based on terrain, weather, nutrition, and fitness level.
