Why use speed instead of pace?
Speed is useful for treadmills and comparing running to other activities like cycling.

What this calculator does
A running speed calculator converts pace (min/mile or min/km) to speed (mph or km/h). Speed is useful for treadmill settings, comparing to other activities, and understanding relative intensity.
How it works
Enter pace. Calculator inverts to speed: 60 ÷ pace (min/mile) = mph.
Formula
Speed (mph) = 60 ÷ Pace (min/mile). Speed (km/h) = 60 ÷ Pace (min/km). Example: 10:00/mile = 6 mph.
Tips for using this calculator
- Treadmills display speed, so convert pace for indoor training
- Speed makes comparing activities easier
- Elite marathon pace (~4:45/mile) is ~12.6 mph
- Walking speed is typically 3-4 mph
- Wind and terrain don't affect treadmill speed but do affect outdoor pace
Frequently asked questions
What treadmill speed equals my outdoor pace?
Use conversion: 60 ÷ pace. 10:00/mile = 6.0 mph. 8:00/mile = 7.5 mph.
Why does the same speed feel harder on a treadmill?
Perception varies. Treadmills lack wind cooling and terrain variation. Add 1% incline to simulate outdoor running.
