How the Pace Calculator Works
Pace Formula: Pace = Total Time / Distance
For example, running 5K (3.1 miles) in 25 minutes gives a pace of 25 / 3.1 = 8:04 per mile.
Pace to Speed
Speed (mph) = 60 / Pace (min/mile)
Mile to KM
Pace/km = Pace/mile / 1.609
Common Running Paces
| Description | Pace/Mile | Pace/KM | Speed |
|---|---|---|---|
| Walking | 20:00 | 12:26 | 3.0 mph |
| Brisk Walk | 15:00 | 9:19 | 4.0 mph |
| Beginner Jog | 12:00 | 7:27 | 5.0 mph |
| Casual Run | 10:00 | 6:13 | 6.0 mph |
| Intermediate | 8:00 | 4:58 | 7.5 mph |
| Advanced | 7:00 | 4:21 | 8.6 mph |
| Elite | 5:00 | 3:06 | 12.0 mph |
Quick Answer
Pace is time per distance unit (minutes per mile or km). Calculate: Pace = Time / Distance. A 30-minute 5K = 9:39/mile or 6:00/km. Conversely, finish time = Pace × Distance. Enter any two values at practicalwebtools.com to calculate the third.
Key Facts
- Pace = Time / Distance (min/mile or min/km)
- 1 mile = 1.609 km; 1 km = 0.621 miles
- Easy pace: conversational, 60-70% max HR
- Tempo pace: comfortably hard, 80-90% max HR
- Average 5K pace: 10-12 min/mile for recreational runners
- Marathon pace is typically 1-2 min/mile slower than 5K pace
- Negative splits: running second half faster (recommended strategy)
Frequently Asked Questions
Running pace is the amount of time it takes to cover a specific distance, typically expressed as minutes per mile or minutes per kilometer. A faster pace means a shorter time per distance unit. For example, a 8:00/mile pace means you run each mile in 8 minutes.
Divide your total running time by the distance covered. If you ran 3 miles in 24 minutes, your pace is 24/3 = 8 minutes per mile. Our calculator handles all the conversions between miles, kilometers, and different time formats automatically.
A good beginner pace is typically 10-12 minutes per mile (6:15-7:30 per km). The key is maintaining a conversational pace where you can speak in full sentences. As fitness improves, most runners can achieve 8-10 minute miles with consistent training.
Race pace predictions estimate finish times for different distances based on your current fitness. Generally, pace slows as distance increases. If you run a 25-minute 5K (8:03/mi), you might expect a 52-minute 10K (8:23/mi) and a 1:55 half marathon (8:47/mi).
Speed (mph or km/h) is the inverse of pace. A 10:00/mile pace equals 6 mph. A 6:00/mile pace equals 10 mph. Speed is useful for treadmill settings and comparing to cycling or other activities. Pace is more intuitive for planning runs.
