Formula

The calculator above works out your average pace (time per kilometre) and average speed (kilometres per hour) from a finish time and distance. The formulas are:

  • Average pace = finish time (minutes) ÷ distance (km) — result in min/km
  • Average speed = distance (km) ÷ (finish time (minutes) ÷ 60) — result in km/h

Where:

  • t = finish time in minutes
  • d = distance in kilometres

Worked Example

Using the default values of 50 minutes and 10 km:

  1. Average pace = 50 ÷ 10 = 5.00 min/km
  2. Average speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

So a 10 km run finished in 50 minutes gives a pace of 5 minutes per kilometre and an average speed of 12 km/h.

Why Your Pace and Speed Differ

Pace and speed are two ways of expressing the same effort. Pace tells you how long each kilometre takes; speed tells you how many kilometres you cover in an hour. Runners and walkers usually track pace (min/km or min/mile), while cyclists and drivers track speed (km/h or mph). The calculator works for any distance and time, but it assumes you keep a constant pace — real-world efforts vary with hills, stops, and fatigue.

How to Read the Results

The first output (pace) is your headline number. A lower pace means faster: 4:30 min/km is quicker than 6:00 min/km. The second output (speed) is useful if you want to compare with a bike or car. For example, a 5:00 min/km pace equals 12 km/h. If you train in miles, convert: 1 mile = 1.60934 km, so a 8:00 min/mile pace is roughly 4:58 min/km.

Common Mistakes

  • Mixing units: Entering time in hours instead of minutes (e.g., 1.5 instead of 90) gives a wildly wrong pace. Always convert hours to minutes first.
  • Rounding too early: If you round 50 ÷ 60 to 0.8, you get 12.5 km/h instead of 12.0. Keep full precision until the final step.
  • Using pace for speed: A 5 min/km pace is not 5 km/h — it’s 12 km/h. They are reciprocals.

Limits of the Formula

This calculator assumes steady effort over flat ground. It doesn’t account for elevation gain, terrain, wind, or breaks. For a hilly run, your average pace will be slower than your “even effort� pace. The formula also assumes you finish the entire distance — if you stop mid-route, the time should include the stop for a true average, or exclude it if you want moving pace.

When to Use This Calculator

Use it after a run, ride, or walk to check if you hit your target pace. You can also plan: if you want to finish a 10 km in under 50 minutes, you need a pace faster than 5:00 min/km. For interval training, calculate each repeat’s pace separately. For long distances, many athletes use pace bands or apps, but this calculator gives a quick check without opening a spreadsheet.

Frequently Asked Questions

How do I convert min/km to min/mile?

Multiply the pace in min/km by 1.60934. For example, 5:00 min/km × 1.60934 = 8:03 min/mile. To go the other way, divide by 1.60934.

What is a good running pace for a beginner?

It varies by age, fitness, and gender. A common conversational pace for a beginner is around 7:00–8:00 min/km (11–13 min/mile). Focus on effort rather than a number; you should be able to talk in short sentences.

Does the calculator work for walking?

Yes. Walking pace is typically 10–15 min/km (16–24 min/mile). Enter your walking time and distance the same way.

Why is my GPS distance different from the course distance?

GPS devices measure your actual path, which includes weaving and turns, so they often record slightly more than the official course distance. That makes your pace appear slower. For accuracy, run the tangents and use a calibrated course.

How do I calculate pace for a marathon?

Enter the marathon distance (42.195 km) and your target finish time in minutes. For a 4-hour marathon, enter 240 minutes and 42.195 km — the calculator gives 5:41 min/km (9:09 min/mile).
