Treadmill Pace Calculator: Convert Speed to Pace
Treadmills are useful, but the numbers can be annoying. Your running training plan may say 6:00 per kilometre or 9:30 per mile, while the treadmill asks for km/h or MPH.
This calculator converts treadmill speed to pace, pace to treadmill speed, and shows your estimated distance, race times, and incline gain for a workout.
Quick answer: how to convert treadmill speed to running pace
To convert treadmill speed to pace, divide 60 by the speed. For example, 6.0 MPH is 10:00 per mile because 60 divided by 6 is 10. In metric, 10 km/h is 6:00 per kilometre because 60 divided by 10 is 6.
Use 0% incline for normal easy treadmill runs if that feels right. Use 1% as a simple starting point when you want a slightly more outdoor-like effort, especially for faster workouts. It is not required for every runner or every run.
Treadmill Pace Calculator
Convert treadmill speed to pace, or convert a target pace into treadmill speed.
How to use this treadmill pace calculator
Use the first tab if you know the treadmill speed. Use the second tab if your training plan gives you a target pace.
- Speed to pace: enter MPH or km/h and the calculator shows min/mile and min/km.
- Pace to speed: enter a target pace and the calculator shows the treadmill speed to set.
- Workout duration: add time if you want estimated distance and elevation gain.
- Incline: use the grade shown on the treadmill. A 1% incline means one metre of rise for every 100 metres forward.
Round the result to a treadmill speed you can actually set. Most treadmills move in 0.1 MPH or 0.1 km/h steps. If you are using this for a race workout, you can also compare the result with your running training zones.
Treadmill speed chart
This quick chart helps when you do not want to pull out a calculator mid-run.

Treadmill pace formulas
MPH to min/mile
Divide 60 by MPH.
Example: 6 MPH equals 10:00 per mile.
km/h to min/km
Divide 60 by km/h.
Example: 10 km/h equals 6:00 per kilometre.
Min/mile to MPH
Divide 60 by your pace in minutes per mile.
Example: 8:00 per mile equals 7.5 MPH.
Min/km to km/h
Divide 60 by your pace in minutes per kilometre.
Example: 5:00 per kilometre equals 12 km/h.
Should you use 1% incline on the treadmill?
A 1% incline is a useful starting point, but it is not a rule you must follow every time. For easy runs, 0% to 1% is usually fine. If 1% makes your easy run feel too hard, lower it and keep the effort easy.
For faster workouts, 1% can make the treadmill feel a little closer to outdoor running. For hill training, use incline on purpose, but do not make every treadmill run a hill workout.
- 0% incline: good for easy runs, warm ups, recovery runs, and beginners.
- 1% incline: a simple default for steady runs and many faster treadmill workouts.
- 2% to 3% incline: useful for gentle hill work or adding variety.
- 4% or higher: treat this as hill training, not normal running.
If the goal is an easy aerobic day, the 80/20 running rule still applies. Do not turn an easy treadmill run into a hard workout just because the incline is available.
Practical note
If you are training for a road race, do some runs outside when you can. The treadmill is great for control, but it does not fully copy wind, turns, footing, downhill running, and race-day pacing.
Beginner treadmill settings
New runners do not need a perfect speed. You need a pace you can repeat without feeling wrecked. If you are not ready to run continuously, start with a run/walk calculator and use the treadmill to control the intervals.
| Goal | Starting setting | What it should feel like | When to increase |
|---|---|---|---|
| Brisk walk | 3.0 to 4.0 MPH / 4.8 to 6.4 km/h | You can talk, but you are not strolling. | When 20 to 30 minutes feels easy. |
| Run/walk | Easy jog plus walk breaks | The jog should feel controlled, not like a sprint. | When the final interval feels like the first few. |
| Easy jog | 4.5 to 6.0 MPH / 7.2 to 9.7 km/h | You can say short sentences. | When you can finish and recover well the next day. |
| First 5K build | Comfortable jog, 0% to 1% incline | You should not need to grip the rails. | Increase duration before speed. |
Do not hold the rails while running
If you need to hold the rails, the speed or incline is probably too high. Slow the treadmill down and run naturally.
Treadmill workouts by goal
Use the calculator above to set the speed. For more exact workout paces, compare your result with the running training zones calculator.
| Workout | How to set it up | Who it is for |
|---|---|---|
| Easy run | 20 to 45 minutes at a pace where you can talk. Use 0% to 1% incline. | Most runners, most weeks. |
| Beginner run/walk | Alternate 30 to 90 seconds jogging with 60 to 120 seconds walking. | New runners and runners returning after time off. |
| Goal race pace | Warm up, then run short blocks at goal pace. Start with 3 to 5 minutes at a time. | Runners learning what race pace feels like. |
| Tempo run | Warm up, then run 10 to 20 minutes at a controlled hard pace. | Runners building speed endurance. |
| Hill workout | Use 2% to 5% incline for short controlled repeats. Keep the speed manageable. | Runners building strength without sprinting. |
If you are using the treadmill to practise a race goal, use the race time calculator first, then bring that target pace back here to find the treadmill speed.
Common treadmill pace mistakes
- Setting the speed too fast: if your easy run feels like a workout, slow down.
- Making every run 1% incline or higher: incline is useful, but easy effort still matters.
- Gripping the rails: this changes your stride and makes the workout less like running.
- Never running outside before a race: use the treadmill, but still practise outdoor pacing when possible.
- Trusting treadmill distance perfectly: treadmill calibration can vary. Use it as a good guide, not a lab tool.
- Jumping off a moving belt: slow it down first. Safety matters more than saving a few seconds.
Treadmill pace calculator FAQ
What treadmill speed is a 10-minute mile?
A 10-minute mile is 6.0 MPH, which is about 9.7 km/h. It is about 6:13 per kilometre.
What treadmill speed is 6:00 per kilometre?
A 6:00 per kilometre pace is 10 km/h, which is about 6.2 MPH.
Should I set the treadmill to 1% incline?
Sometimes. A 1% incline is a reasonable starting point for a slightly more outdoor-like effort, especially for faster workouts. It is not required for every easy run.
Is treadmill pace the same as outdoor pace?
Not always. Treadmill running removes wind, turns, and uneven ground, but it also locks you into one speed. Some runners find it easier, while others find it harder mentally or physically.
Why does treadmill pace feel harder than outside?
The fixed belt speed can make you hold a pace without the small natural changes you make outside. Heat, poor airflow, boredom, and treadmill calibration can also make it feel harder.
Can beginners use this treadmill calculator?
Yes. Beginners can use it to set a comfortable walk, jog, or run/walk pace. Start slower than you think and increase duration before speed.
Bottom line
Use this treadmill pace calculator when your plan gives you a pace but the treadmill gives you speed. Set the speed, keep the effort honest, and use incline with a purpose instead of making every run harder than it needs to be.
