Understanding Running Pace and Velocity
Running pace is the most common metric used by runners to measure intensity and track progress. Unlike speed (km/h or mph), pace tells you how many minutes it takes to cover a single unit of distance (min/km or min/mi). This makes it easier to manage effort during long runs, intervals, or races.
Our Running Pace Calculator helps you solve for three variables: Pace, Distance, or Time. If you know how far you want to run and how much time you have, we'll give you the required pace. If you know your target pace and goal distance, we'll calculate the finish time.
Different training sessions require different paces. Your easy run pace should feel genuinely comfortable — typically 60–70% of your maximum heart rate, or roughly 90 seconds to 2 minutes per kilometre slower than your 5K race pace. Tempo runs are done at your lactate threshold, around 25–30 seconds per kilometre faster than your marathon race pace. Interval workouts target your VO2max, usually run close to your 5K race pace.
If you are training in miles but racing in kilometres — or vice versa — our calculator handles both. Enter your known values in either unit and the result updates automatically. Bookmark the calculator so it is always one tap away during your workout planning sessions.
How does this work?
What is the difference between Pace and Speed?
Speed measures distance over time (e.g., 12 km/h), while Pace measures time over distance (e.g., 5:00 min/km). Runners prefer pace because it matches how race courses are marked and how we feel our rhythm during the run.
How do I improve my running pace?
Consistency is key. Mix easy runs for aerobic base building with interval training and tempo runs to improve your lactate threshold. Using a pace calculator helps you set realistic targets for these different types of workouts.
What is a good pace for a beginner runner?
There is no single answer — it depends on fitness level and distance. A beginner completing their first 5K typically runs at 7:00–9:00 min/km (11:00–14:30 min/mi). The most important thing is to run at a pace where you can hold a full conversation. Speed comes with consistency over weeks and months, not days.
