How to Calculate Running Pace
Quick Answer
Pace = Time ÷ Distance
- Pace in min/km: Total minutes ÷ Distance in km
- Pace in min/mile: Total minutes ÷ Distance in miles
- Speed (km/h) = 60 ÷ Pace (min/km)
Example: You run 5 km in 28 minutes. Pace = 28 ÷ 5 = 5.6 min/km = 5:36 per km = 9:01 per mile. Speed = 60 ÷ 5.6 = 10.71 km/h.
Running pace connects time, distance and speed. Whether you are training for your first 5K, targeting a personal best at a half marathon or simply trying to run more consistently, understanding pace gives you a reliable training framework.

Pace, Speed and Time: The Three Formulas
- Pace (min/km) = Total time in minutes ÷ Distance in km
- Speed (km/h) = Distance in km ÷ Time in hours
- Race time = Pace (min/km) × Distance (km)
- Speed (km/h) = 60 ÷ Pace (min/km)
- Pace (min/km) = 60 ÷ Speed (km/h)
To convert pace: min/km × 1.60934 = min/mile. Example: 5:36 per km × 1.609 = 9:01 per mile.
Pace to Finish Time Table
| Pace (min/km) | 5K | 10K | Half Marathon | Full Marathon |
|---|---|---|---|---|
| 4:00 | 19:59 | 41:59 | 1:24:17 | 2:48:34 |
| 4:30 | 22:30 | 45:00 | 1:34:47 | 3:09:33 |
| 5:00 | 25:00 | 50:00 | 1:45:17 | 3:30:34 |
| 5:30 | 27:30 | 55:00 | 1:55:48 | 3:51:36 |
| 6:00 | 30:00 | 60:00 | 2:06:20 | 4:12:40 |
| 6:30 | 32:30 | 65:00 | 2:16:50 | 4:33:41 |
| 7:00 | 35:00 | 70:00 | 2:27:21 | 4:54:42 |
| 7:30 | 37:30 | 75:00 | 2:37:52 | 5:15:43 |

Running Pace and Training Zones
- Easy or recovery pace: Conversational pace. 60 to 75% of maximum heart rate. Builds aerobic base. Should make up 70 to 80% of total weekly running.
- Aerobic or base pace: Comfortable but purposeful. 75 to 80% of max heart rate.
- Tempo or threshold pace: Comfortably hard. 80 to 90% of max heart rate. Typically 20 to 40 seconds per km faster than easy pace.
- Interval or VO2 max pace: Hard effort. 90 to 95% of max heart rate. Short bursts with recovery.
- Sprint or race pace: Near maximum effort. Over 95% of max heart rate.
Common Race Distances by Country
- 5K parkrun (UK, Australia, South Africa): Free, timed, held weekly in parks. Average finishing time approximately 31 minutes (6:12 per km).
- 10K (all countries): Most common paid race distance globally. Average finisher approximately 55 to 65 minutes.
- Half marathon 21.1 km: Popular in India (Mumbai, Delhi marathons) and Pakistan (Lahore marathon). Average 2:15 to 2:30.
- Full marathon 42.2 km: Major events: London, New York, Boston, Mumbai, Sydney. Average 4:30 to 5:00 globally.
Frequently Asked Questions
What is a good running pace for a beginner?
A good beginner running pace is one that lets you hold a conversation while running. This is typically 7:00 to 9:00 min/km (11:15 to 14:30 min/mile). Speed is irrelevant when starting out. Building the ability to run continuously for 20 to 30 minutes is the first goal.
What is a good 5K time?
Under 30 minutes (6:00 per km pace) is good for a recreational runner. Under 25 minutes (5:00 per km) is above average. Under 20 minutes (4:00 per km) is competitive.
How do I convert my pace from min/km to min/mile?
Multiply your min/km pace by 1.60934 to get min/mile. For example, 5:30 per km = 5.5 × 1.60934 = 8.85 minutes per mile = approximately 8:51 per mile.
How do I calculate my marathon finish time from my 10K time?
A common rule of thumb is marathon time = 10K time × 4.65. For example, a 50-minute 10K suggests a marathon time of approximately 50 × 4.65 = 232.5 minutes = 3:52:30.
