Set the treadmill from your pace plan
Treadmill sessions are usually controlled by speed, while training plans are often written as pace. Use this calculator to move between km/h, mph, min/km and min/mile before you start the belt.
For outdoor-style effort indoors, many runners add a small incline and keep the speed tied to the workout target rather than guessing from feel.
Treadmill setting examples
12 km/h treadmill
5:00/km
A clear steady setting when the treadmill is in metric units.
7.5 mph treadmill
8:00/mile
A common mile-based setting for indoor progression runs.
15 km/h treadmill
4:00/km
Equivalent to 20-minute 5K pace.
When this helps indoors
- Your workout says 5:00/km but the treadmill asks for km/h.
- You are using a hotel or gym treadmill set to mph.
- You want interval speeds ready before the session starts.
- You are matching indoor workouts to 5K, 10K or marathon pace.
Common treadmill speeds for runners
Use these as quick checks when a treadmill only shows one speed unit. Exact effort still depends on incline, belt feel and heat indoors. Many runners use 1% incline to make treadmill running feel closer to outdoor effort, especially at faster speeds.
| Pace | Treadmill speed km/h | Treadmill speed mph | Common use |
|---|---|---|---|
| 8:00/km | 7.50 | 4.66 | Easy walk-jog |
| 6:00/km | 10.00 | 6.21 | Easy run |
| 5:00/km | 12.00 | 7.46 | Steady run |
| 4:30/km | 13.33 | 8.28 | Tempo |
| 4:00/km | 15.00 | 9.32 | Fast running |

Frequently asked questions
How do I convert treadmill speed into running pace?
You can convert treadmill speed into running pace by converting km/h or mph into minutes per kilometre or mile. Faster treadmill speeds produce lower pace times.
What treadmill speed is 5 min/km?
A pace of 5:00 per kilometre equals approximately 12 km/h or 7.46 mph on a treadmill.
Is treadmill running harder than outdoor running?
Treadmill running can feel slightly easier because there is less wind resistance, although incline settings can help simulate outdoor conditions.
