Pace Converter – Running Pace Calculator
Whether you're training for a 5K or a marathon, understanding your pace is essential. This pace converter instantly translates between minutes per mile and minutes per kilometer, shows your speed in mph and km/h, and estimates your finish times for popular race distances.
How Running Pace Works
Running pace is expressed as the time it takes to cover one unit of distance — either one mile or one kilometer. A pace of 8:30 per mile means you run one mile in 8 minutes and 30 seconds.
1 mile = 1.60934 kilometers
To convert min/mile to min/km, divide by 1.60934. To convert min/km to min/mile, multiply by 1.60934.
For example, 8:30/mile = 5:17/km, and the equivalent speed is about 7.1 mph or 11.3 km/h.

Race Distance Reference
| Race | Distance (km) | Distance (miles) | 8:30/mi Finish |
|---|---|---|---|
| 5K | 5.0 | 3.1 | 26:23 |
| 10K | 10.0 | 6.2 | 52:47 |
| Half Marathon | 21.1 | 13.1 | 1:51:23 |
| Marathon | 42.2 | 26.2 | 3:42:46 |
Training Pace Zones
Understanding pace zones helps runners train at the right intensity:
- Easy / Recovery: 1–2 minutes slower than race pace. Used for 80% of training volume.
- Tempo / Threshold: About 25–30 seconds slower than 5K pace per mile. Sustainable for 20–40 minutes.
- Interval: Near or faster than 5K pace. Short bursts with recovery between sets.
- Sprint: Maximum effort for 100–400 meters.
Most running coaches recommend the 80/20 rule: 80% of your weekly mileage at easy pace and 20% at harder efforts.
Tips for Improving Your Pace
- Consistency over intensity: Running regularly at easy pace builds aerobic fitness more effectively than occasional hard runs
- Add one speed session per week: Tempo runs or intervals gradually improve your lactate threshold
- Don't neglect rest days: Recovery is when your body adapts and gets stronger
- Increase mileage gradually: Follow the 10% rule — don't increase weekly mileage by more than 10% per week
- Race-day pacing: Start slightly slower than goal pace and negative-split (run the second half faster)
Frequently Asked Questions
How do I convert minutes per mile to minutes per km?
Divide your pace in minutes per mile by 1.60934. For example, 8:00/mile ÷ 1.60934 = 4:58/km. Or use the converter above to get instant results.
What is a good running pace for beginners?
A good beginner pace is 10:00–12:00 per mile (6:13–7:27 per km). The most important thing is consistency and being able to hold a conversation while running.
How fast is a 4-hour marathon pace?
A 4-hour marathon requires a pace of about 9:09 per mile or 5:41 per km, which is approximately 6.55 mph.
What is the world record marathon pace?
Kelvin Kiptum's world record marathon (2:00:35) was run at approximately 4:34 per mile or 2:51 per km — an average speed of 13.1 mph (21.1 km/h).
Should I train by pace or heart rate?
Both have value. Pace is straightforward and easy to measure on flat terrain. Heart rate accounts for hills, heat, and fatigue. Many runners use a combination of both for optimal training.
