Calculate Pace
What is Running Pace?
Running pace is the time needed to cover a unit of distance, usually expressed in minutes per kilometer (min/km) or minutes per mile (min/mi). It's a fundamental metric for runners to plan workouts and race strategies, being more intuitive than speed (km/h) for controlling effort during runs.
Pace (min/km) = 60 / Speed (km/h)
How to Calculate Pace?
Pace is calculated by dividing total time by distance covered. For example, if you ran 10 km in 50 minutes, your pace was 5:00 min/km. Alternatively, you can convert speed to pace: 12 km/h equals a 5:00 min/km pace. The calculator also estimates times for standard distances assuming constant pace, although in practice pace varies during long races.
Frequently Asked Questions
What is a good running pace?
It depends on your level and goal. Beginners typically run 6:00-8:00 min/km. Intermediate runners 5:00-6:00 min/km. Advanced runners under 4:30 min/km. For marathons, elite athletes maintain 3:00 min/km pace (21 km/h), while average runners are between 5:30-7:00 min/km.
How can I improve my running pace?
To improve pace: (1) high-intensity interval training, (2) long runs at comfortable pace for aerobic base, (3) tempo/threshold runs, (4) strength training, (5) weight loss if needed, (6) adequate rest for recovery. Improvement is gradual and requires consistency.
Should I use pace or speed?
Runners generally prefer pace (min/km) because it's more practical during runs - it's easier to think 'I'll maintain 5 min/km' than '12 km/h'. Speed is more used on treadmills and in scientific analysis. The choice is personal, but pace is the standard in road running.
Why does pace vary during long races?
In long races (marathon, ultra), muscle fatigue, glycogen depletion, dehydration, and mental stress gradually reduce pace. Strategies include starting conservatively (negative split) or maintaining constant pace. Long training runs teach the body to conserve energy and maintain pace.
What is training pace vs race pace?
Race pace is the maximum sustainable for the target distance. Training paces vary: recovery runs are 1-2 min/km slower than race pace, long runs are ~30-60s/km slower, threshold runs are close to 1-hour race pace, intervals are faster than 5K pace.
