This pace calculator helps runners, walkers, and cyclists convert between pace, time, and distance. Enter any two values and the calculator will find the third, while also showing pace in both metric and imperial units.
- Calculate pace: Enter distance and time to find your average pace per kilometre and per mile.
- Calculate time: Enter distance and pace to see how long it will take to complete your run.
- Calculate distance: Enter pace and time to estimate how far you will go.
- Convert units: See results in min/km, min/mile, km/h, and mph.
- Race projections: Estimate finish times for 5K, 10K, half marathon, and marathon distances.
How to use: In Simple mode, enter your distance and total time to get your average pace. In Advanced mode, enter any two values (distance, time, pace) to solve for the third. This makes it ideal for training, race planning, or tracking progress.

Pace Calculator
Calculate running pace, time, or distance. Enter any two values and the calculator finds the third.
How the pace calculator works
The pace calculator uses the relationship between distance, time, and pace to solve for the missing value. The basic formula is:
- Pace = Time ÷ Distance
- Time = Pace × Distance
- Distance = Time ÷ Pace
The calculator also converts results into both metric (km, min/km, km/h) and imperial (miles, min/mile, mph) units.
Worked examples
- Find pace: A 10 km run completed in 50 minutes → 50 ÷ 10 = 5:00 min/km.
- Find time: Pace of 6:00 min/km over 5 km → 6 × 5 = 30 minutes.
- Find distance: 45 minutes at 5:30 min/km → 45 ÷ 5.5 = 8.18 km.
Pace conversion table
This table shows common running paces with equivalent speeds and times:
| Pace (min/km) | Pace (min/mile) | Speed (km/h) | 5K Time | 10K Time |
|---|---|---|---|---|
| 4:00 | 6:26 | 15.0 | 20:00 | 40:00 |
| 5:00 | 8:03 | 12.0 | 25:00 | 50:00 |
| 6:00 | 9:39 | 10.0 | 30:00 | 60:00 |
| 7:00 | 11:16 | 8.6 | 35:00 | 70:00 |
| 8:00 | 12:52 | 7.5 | 40:00 | 80:00 |
Why pace matters in training
Pace is a key metric for runners, walkers, and cyclists. It helps set training intensity, compare performance across distances, and plan race strategies. Consistent pacing also improves endurance and prevents burnout.
Limitations of pace calculators
A pace calculator provides accurate math, but it does not account for real-world conditions. Factors like terrain, weather, fitness level, and hydration can affect actual performance. Use it as a planning guide, not a guarantee of results.
Pace Calculator FAQs
Pace per kilometre is calculated by dividing total time by distance in kilometres. Example: 50 minutes ÷ 10 km = 5:00 min/km.
A good running pace depends on fitness level and experience. Beginners may run 7–8 min/km, while advanced runners often train between 4–5 min/km.
Speed is 60 divided by pace (in minutes per kilometre). Example: 5:00 min/km pace equals 12 km/h.
No. Pace is always a positive value representing minutes per kilometre or mile. If you see a negative pace, it means the input values were incorrect.
Pace helps runners track progress, plan race strategies, and train at the right intensity. It is one of the most important metrics for endurance sports.
Pace is your average time per unit of distance, while a split is the time it takes to complete a specific segment of a run, such as each kilometre or mile.
Yes. Walking pace is calculated the same way as running pace—time divided by distance.
