About Pace Calculator
Use this pace calculator for running, walking, cycling, or race planning. Choose what you want to find, enter two known values, and get pace plus related speed conversions.
How to Use
Choose whether to find pace, time, or distance.
- Select the value you want to calculate.
- Enter the two remaining values.
- Review pace per mile, pace per kilometer, speed, time, and distance.
Examples
-
Calculate running pace
Find: Pace Time: 01:20:00 Distance: 5 miles Pace: 16:00 per mile Metric pace: 09:57 per km Speed: 3.75 mph Distance conversion: 8.05 km
-
Calculate finish time
Find: Time Distance: 10 km Pace: 05:00 per km Finish time: 50:00 Pace: 08:03 per mile Speed: 7.46 mph Distance conversion: 6.21 miles
Real-World Usage Scenarios
- Sub-Target Race Planning - Determine the exact pace required to break specific time barriers, such as a sub-4-hour marathon or a sub-20-minute 5K.
- Track Interval Splits - Calculate precise time targets for shorter track distances like 400m or 800m repeats during speed work sessions.
- Treadmill-to-Road Adjustment - Convert treadmill speed settings (MPH or KPH) into running pace (min/mile or min/km) to maintain training consistency outdoors.
- Post-Run Performance Review - Input your total elapsed time and GPS-measured distance to verify your official average pace for training logs.
Frequently Asked Questions
What is the difference between pace and speed?
Pace measures the time it takes to cover a specific distance (e.g., minutes per kilometer), whereas speed measures distance covered over time (e.g., kilometers per hour).
How should I input my race time?
Use the hh:mm:ss format for long distances (e.g., 03:45:00 for a marathon) or mm:ss for shorter sprints.
Does the tool support both metric and imperial units?
Yes. You can input distance in kilometers, miles, or meters. Results automatically display both minutes per mile and minutes per kilometer.
Can I calculate distance based on a target pace?
Yes. Select 'Distance' as the value to find, then enter your planned pace and total workout duration.
