Treadmill Pace Calculator
Quickly convert between treadmill speed in km/h and running pace in min/km. If you train on a treadmill and race outdoors, this calculator helps you match your indoor effort to outdoor pace, with incline adjustments to simulate real-world conditions.

Set to 1% to simulate outdoor running
How It Works
The conversion is straightforward: pace (min/km) = 60 / speed (km/h). For example, 10 km/h equals 6:00 min/km. Running on an incline increases effort, so the adjusted outdoor equivalent pace accounts for gradient: the calculator uses the formula adjustedPace = pace x (1 - incline% x 0.03), meaning a 1% incline makes your effective pace roughly 3% faster than flat running.
Quick Reference
| Speed (km/h) | Pace (min/km) | 5K Time | 10K Time | Activity |
|---|---|---|---|---|
| 5.0 | 12:00 | 1:00:00 | 2:00:00 | Slow walk |
| 6.0 | 10:00 | 50:00 | 1:40:00 | Brisk walk |
| 7.0 | 8:34 | 42:51 | 1:25:43 | Fast walk / slow jog |
| 8.0 | 7:30 | 37:30 | 1:15:00 | Easy jog |
| 9.0 | 6:40 | 33:20 | 1:06:40 | Moderate jog |
| 10.0 | 6:00 | 30:00 | 1:00:00 | Steady run |
| 11.0 | 5:27 | 27:16 | 54:33 | Tempo run |
| 12.0 | 5:00 | 25:00 | 50:00 | Fast run |
| 13.0 | 4:37 | 23:05 | 46:09 | Race pace |
| 14.0 | 4:17 | 21:26 | 42:51 | Fast race pace |
| 15.0 | 4:00 | 20:00 | 40:00 | Sprint intervals |
Times assume flat (0%) incline. Add 1% incline to match outdoor running effort.
Frequently Asked Questions
- What treadmill speed is 5:00 min/km?
- A pace of 5:00 min/km equals 12.0 km/h on the treadmill. This is a solid running pace suitable for tempo runs and is close to the speed many competitive recreational runners train at.
- Should I set the treadmill to 1% incline?
- Many coaches recommend a 1% incline to simulate wind resistance encountered outdoors. Research by Jones and Doust (1996) found that 1% grade most closely matches the energy cost of outdoor running at speeds above 10 km/h.
- Is treadmill running easier than outdoor running?
- Treadmill running eliminates wind resistance and the belt assists leg turnover, making it slightly easier at the same speed. A 1% incline compensates for this difference. However, treadmills offer a more controlled, joint-friendly surface.
- What speed is a brisk walk on a treadmill?
- A brisk walk is typically 5.5–6.5 km/h (about 9:10–10:55 min/km). Most people transition from walking to jogging between 6.5 and 8.0 km/h.
Treadmill Speed-Pace Conversion

- 0.03
- = Effort adjustment factor per 1% incline
The incline adjustment approximates the added effort of running uphill. At 1% incline, the treadmill effort roughly matches flat outdoor running. Higher inclines significantly increase energy expenditure.
