Calculate pace, time, or distance for any run or race distance
Tracking health metrics shouldn't require doctor visits for every quick estimate. Running Pace Calculator lets you calculate pace, time, or distance for any run or race distance instantly with science-backed formulas. All calculations run in your browser, and no personal health data is stored or transmitted anywhere.
Running pace is the time it takes to cover one unit of distance, typically expressed as minutes per kilometer (min/km) or minutes per mile (min/mi). It's the inverse of speed. A pace of 5:00/km means you run 1 kilometer in exactly 5 minutes, which equals 12 km/h or about 7.5 mph.
Improve pace through: interval training (short fast bursts with recovery), tempo runs (sustained comfortably hard effort for 20–40 min), consistent weekly mileage build-up, and strength training for running economy. Most coaches recommend 80% of training at easy pace and 20% at higher intensity. Improvement takes 4–8 weeks of consistent training to show.
Common race paces for recreational runners: 5K — 5:00–7:00/km; 10K — 5:20–7:30/km; Half Marathon — 5:40–8:00/km; Marathon — 6:00–8:30/km. Elite runners run 5K in under 2:40/km and marathons in under 3:00/km. Focus on your own improvement rather than comparing to others.
