What is running pace?
Running pace is the time it takes to cover one kilometer (or mile) while running. It is typically expressed in minutes per kilometer (min/km). For example, a pace of 5:00 min/km means you run each kilometer in exactly 5 minutes. Pace is the most common metric runners use to measure effort and plan race strategies.
How to calculate running pace?
Running pace is calculated by dividing total running time by the distance covered:
Pace = Total time ÷ Distance
For example, if you ran 10 km in 50 minutes, your pace is 50 ÷ 10 = 5:00 min/km. This calculator also converts pace to speed in km/h for easier comparison.
What is the pace formula?
There are three related formulas depending on what you want to calculate:
- Pace = Time ÷ Distance
- Time = Pace × Distance
- Distance = Time ÷ Pace
Speed (km/h) is the inverse of pace: Speed = 60 ÷ Pace (min/km). A pace of 5:00 min/km equals 12 km/h.
Running pace calculation examples
5K race in 25 minutes: Pace = 25 ÷ 5 = 5:00 min/km (12 km/h)
10K race in 55 minutes: Pace = 55 ÷ 10 = 5:30 min/km (10.91 km/h)
Half marathon (21.1 km) in 1:45:00: Pace = 105 ÷ 21.1 = 4:58 min/km (12.06 km/h)
Marathon (42.2 km) in 3:30:00: Pace = 210 ÷ 42.2 = 4:59 min/km (12.06 km/h)
What is a good running pace?
A "good" pace depends on your fitness level, age, and running experience:
- Beginner runners: 7:00–8:00 min/km
- Intermediate runners: 5:30–6:30 min/km
- Advanced runners: 4:30–5:30 min/km
- Elite runners: under 3:30 min/km
When to use a running pace calculator?
A pace calculator is useful for planning race goals, estimating finish times for different distances, tracking training progress, and determining target paces for interval workouts. Whether you are training for a 5K or a marathon, knowing your pace helps you run smarter and avoid starting too fast.
