Make each run count, without chasing a magic pace.
Your running pace is simply how long it takes to cover one kilometer or mile. It can help you plan a race or compare sessions, but it cannot tell you how hard you personally worked.
- Easy effort is different for a beginner and an experienced runner.
- Hills, weather, fatigue, and terrain all affect pacing.
- Running longer races often requires slowing down compared with a short race.
Common race comparisons
If you could hold exactly this pace for the whole distance:
Actual race times often differ, especially for half marathons and marathons. These are not individualized finish-time predictions.

How running pace works
Pace is time divided by distance. For example, 30 minutes to run 5 km means an average pace of 6:00 min/km, equivalent to roughly 9:39 min/mile or 10 km/h. A lower minutes-per-kilometer value means faster running.
For a race target, multiply pace by distance to estimate finish time at an unchanging pace. Real running times change with endurance, conditions, and terrain. Explore our guide to running for weight loss or compare cardio and weight training.
What about running calories?
When body weight is supplied, the tool also shows a rough exercise-energy estimate based on a representative MET for the calculated speed. It separates total (gross) energy from the approximate amount above resting (active) energy.
These numbers are not a food allowance and don’t translate directly to grams of body fat lost. Energy needs and weight change are more complex. See the Adult Compendium of Physical Activities and our exercise and weight loss guide for more context.
