Treadmill Pace Calculator: Convert Speed to Pace
Convert treadmill MPH or km/h to running pace, or enter a target pace to find the treadmill speed to set. Add workout details only if you also want distance and estimated equivalent climb.

Quick treadmill pace conversion
Speed to pace: divide 60 by speed. At 6.0 MPH, 60 ÷ 6 = 10:00 per mile. At 10 km/h, 60 ÷ 10 = 6:00 per kilometre.
Pace to speed: divide 60 by your pace in decimal minutes. A 5:00/km pace is 12 km/h. An 8:00/mile pace is 7.5 MPH.

Should you use 1% incline on a treadmill?
A 1% incline can be a useful starting point when you want treadmill running to feel a little closer to outdoor running, especially at faster speeds. It is a guideline, not a rule.
For easy or recovery running, 0% to 1% is usually reasonable if the effort stays easy. If 1% noticeably changes the workout, lower the incline. For hill sessions, use incline on purpose rather than adding it to every run.
- 0%: easy runs, recovery runs, warmups and beginners.
- 1%: a simple option for steady or faster treadmill running.
- 2% to 3%: gentle hill work or variety.
- 4%+: treat it as hill training and adjust speed accordingly.
Treadmill pace is still not exactly outdoor pace
Wind, turns, footing, downhill running, temperature and treadmill calibration all change how a pace feels. If you are training for an outdoor race, include some outdoor running when you can.
Beginner treadmill settings
New runners do not need a perfect number. Start with a speed you can repeat with relaxed form. Increase duration before chasing speed.
Brisk walk
About 3.0 to 4.0 MPH / 4.8 to 6.4 km/h. You should be moving with purpose but still in control.
Run/walk
Use an easy jog plus planned walk breaks. The jog should not feel like a sprint. Try the Run Walk Calculator if you want an interval setup.
Easy jog
Use a conversational effort. A fixed speed range is less useful than choosing a pace that leaves you recovered the next day.
First 5K build
Keep the treadmill controlled, use 0% to 1% incline if comfortable, and build the time you can run before increasing speed.
Do not hold the rails while running
If you need the rails to keep up, reduce the speed or incline and run naturally.
Treadmill workouts by goal
Easy run
20 to 45 minutes at conversational effort. Use 0% to 1% incline if that keeps the run comfortable.
Beginner run/walk
Alternate short jogging blocks with walking. Keep the run portions controlled enough that you can repeat them.
Goal race pace
Warm up, then practise short blocks at goal pace. Use the calculator above to convert that pace into treadmill speed.
Tempo or threshold
Warm up, then run a controlled hard segment. You should not be sprinting or hanging onto the rails.
Hill workout
Use incline as the main stress and keep speed under control. Short repeats at 2% to 5% can be plenty.
Training-plan workout
If your plan gives you a pace, bring it here. If it gives you effort or zones, compare it with the Training Zones Calculator.
Common treadmill pace mistakes
- Setting easy pace too fast: if an easy run feels like a workout, slow down.
- Treating 1% incline as mandatory: incline should serve the workout, not make every run harder.
- Holding the rails: lower the speed or incline instead.
- Trusting treadmill distance perfectly: calibration varies between machines.
- Doing all race preparation indoors: outdoor pacing, turns, wind and footing still matter.
- Jumping off a moving belt: slow the treadmill first.
Treadmill pace calculator FAQ
What treadmill speed is a 10-minute mile?
A 10-minute mile is 6.0 MPH, about 9.7 km/h. That is about 6:13 per kilometre.
What treadmill speed is 6:00 per kilometre?
A 6:00/km pace is 10 km/h, about 6.2 MPH.
Should I set the treadmill to 1% incline?
You can, especially for some faster workouts, but it is not required. Keep easy runs easy and use incline with a purpose.
Is treadmill pace the same as outdoor pace?
Not always. Wind, footing, turns, temperature and treadmill calibration can all change how the same pace feels.
Why can treadmill pace feel harder than outside?
The fixed belt speed removes the small pace changes you naturally make outdoors. Heat, limited airflow, boredom and machine calibration can also affect effort.
Can beginners use this calculator?
Yes. Use it for a comfortable walk, jog or run/walk pace. Increase duration before speed and do not worry about matching someone else’s treadmill setting.
Bottom line
Use the calculator when your plan gives you pace but the treadmill gives you speed, or the other way around. Add duration and incline only when you want workout distance and estimated equivalent climb.
