Pace Calculator
Calculate running pace, time, or distance. Enter any two values to find the third, with split times for your run.
Split Times
| Split | Split Time | Cumulative |
|---|---|---|
| 1 km | 5:00 | 5:00 |
| 2 km | 5:00 | 10:00 |
| 3 km | 5:00 | 15:00 |
| 4 km | 5:00 | 20:00 |
| 5 km | 5:00 | 25:00 |
How It Works
- 1
Choose your calculation mode
Select whether you want to calculate pace, time, or distance. Toggle between metric (km) and imperial (miles) units.
- 2
Enter your known values
Input the two values you know, for example, distance and time to calculate pace. Use race presets (5K, 10K, Half Marathon, Marathon) for quick distance entry.

Understanding Running Pace
Running pace, the time it takes to cover one kilometer or one mile, is the metric distance runners plan around. Speed tells you how fast you are going; pace tells you how long each unit of distance takes, which is what you actually use to plan a race or a training session. Pace, time, and distance form a simple triangle: know any two and you can find the third. A runner finishing a 5K in 25 minutes holds a pace of 5:00 per kilometer (about 8:03 per mile), or 12 km/h (7.46 mph). Pace is also the key to negative splits, the strategy of running the second half faster than the first. Elite marathoners aim for even splits, holding pace within 5–10 seconds per mile across the whole race. The calculator also generates split tables with your projected time at each kilometer or mile marker, so you can set realistic checkpoint targets on race day.
Frequently Asked Questions
How do I calculate my running pace?
Divide your total time by the distance covered. For example, if you ran 5 km in 25 minutes, your pace is 25 ÷ 5 = 5:00 per km (or about 8:03 per mile).
What is a good pace for a beginner runner?
Most beginner runners start at 6:00–7:00 per km (9:40–11:16 per mile). Focus on consistency and gradually improving. A comfortable pace where you can hold a conversation is a good starting point.
How do I convert pace from min/km to min/mile?
Multiply your min/km pace by 1.609344 (the number of km in a mile). For example, 5:00/km × 1.609344 ≈ 8:03/mile. Our calculator does this conversion automatically.
