The keyboard shortcut to save the current webpage in most desktop browsers is Ctrl+S (Windows/Linux) or Command+S (Mac). Pressing it opens the browser’s “Save As” dialog, letting you choose where to store the page and in what format. This works in Chrome, Firefox, Edge, Safari, and Opera, and it’s the fastest way to keep a local copy of a page.
Formula
The calculator computes your average running pace and speed from a finish time and distance. The formulas are simple:
- Pace = finish time (minutes) ÷ distance (km) → result in min/km
- Speed = distance (km) ÷ (finish time (minutes) ÷ 60) → result in km/h
Variables:
- t – finish time in minutes (e.g., 50 min)
- d – distance in kilometers (e.g., 10 km)
Pace tells you how long it takes to cover one kilometer; speed tells you how many kilometers you cover in one hour. Both are standard metrics for runners.
Worked Example
Using the default values from the calculator above:
- Finish time = 50 minutes, distance = 10 km.
- Pace = 50 ÷ 10 = 5.0 min/km.
- Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.0 km/h.
The calculator shows an average pace of 5.00 min/km and an average speed of 12.00 km/h. These match the formulas exactly.
When to Use This Calculator
Use this tool when you’ve completed a run or race and want to know your average pace and speed. It’s especially handy for:
- Planning race goals – e.g., if you want to finish a 10K in under 50 minutes, you need a pace faster than 5:00 min/km.
- Comparing training runs – see if you’re improving by checking pace trends.
- Converting between pace and speed – some apps show one, but you might need the other.
The calculator works for any distance, not just 10K. Enter your own time and distance to get personalized results.
How to Read the Results
The first output, pace, is the headline answer. A pace of 5.00 min/km means you run one kilometer in 5 minutes. Lower pace = faster running. The second output, speed, is the complementary view: 12.0 km/h means you cover 12 kilometers in an hour. Higher speed = faster running.
For comparison, a recreational runner might have a pace around 6–7 min/km, while a competitive runner could be at 4–5 min/km. Elite marathoners run under 3 min/km. These are rough ranges; your own fitness and terrain matter.
If you’re used to miles, note that 1 mile ≈ 1.609 km. To convert pace from min/km to min/mile, multiply by 1.609. For example, 5.00 min/km ≈ 8.05 min/mile.
Common Mistakes and Limitations
- Unit mix-ups: If you enter distance in miles but the calculator expects km, your pace will be wrong. Always convert miles to km (multiply by 1.609) before entering.
- Time format: Enter minutes only, not hours and minutes separately. For a 1 hour 10 minute run, enter 70, not 1:10.
- Rounding: The calculator rounds to two decimals. For pacing, many runners prefer seconds (e.g., 5:30 per km), so you may want to multiply the decimal by 60 to get seconds: 0.50 min = 30 sec.
- Terrain and conditions: The formula assumes a flat, even surface with no wind. Real-world pace varies with hills, heat, and fatigue.
- GPS accuracy: If you use a watch or phone, the distance may be slightly off, affecting the calculation.
Alternatives and Related Metrics
Instead of average pace, you might want:
- Heart rate zones: Pace alone doesn’t show effort. Use a heart rate monitor to see how hard you’re working.
- Cadence: Steps per minute. A higher cadence often reduces injury risk.
- VOâ‚‚max: An estimate of aerobic fitness, often calculated from race times.
If you’re training for a specific race, many running apps (e.g., Strava, Garmin Connect) automatically calculate pace and speed. This calculator is useful for quick manual checks or when you don’t have an app.
Frequently Asked Questions
How do I convert pace from min/km to min/mile?
Multiply the pace in min/km by 1.609. For example, 5.00 min/km × 1.609 = 8.05 min/mile. To get seconds, take the decimal part (0.05) × 60 = 3 seconds, so 8:03 per mile.
What is a good running pace for a beginner?
It varies by age and fitness, but a common starting range is 7–8 min/km (11–13 min/mile). Focus on maintaining a conversational effort rather than a specific number.
Why does my GPS watch show a different pace?
GPS watches use real-time location data, which can be affected by trees, buildings, or signal loss. They also update pace every few seconds, so momentary changes show. The calculator gives an average over the entire run.
Can I use this for walking?
Yes. Enter your walking time and distance. Typical walking pace is 10–12 min/km (16–19 min/mile).
How do I calculate pace for a marathon (42.195 km)?
Enter the distance as 42.195 and your target finish time in minutes. For a 4-hour marathon, enter 240 minutes. The calculator will show your required pace.
