  2. Set your time: Input hours, minutes, and seconds for your run or target finish time
  3. View results: Instantly see your pace per kilometer, pace per mile, and speed in km/h and mph
  4. Use presets: Click 5K, 10K, Half Marathon, or Marathon for common race distances
  5. Copy results: Save your calculations to share with coaches or track in your training log

Understanding Pace vs Speed

Pace and speed measure the same thing from different perspectives:

  • Pace (min/km or min/mile): Shows how many minutes it takes to cover one kilometer or mile, preferred by runners for race planning
  • Speed (km/h or mph): Shows how many kilometers or miles you cover in one hour, useful for comparing with other activities
  • Both metrics are automatically calculated and displayed in this tool for complete performance tracking
  • Slower paces have higher numbers while faster paces have lower numbers (e.g., 4:00/km is faster than 6:00/km)

Common Running Distances and Paces

Use this calculator to plan race paces for standard distances like 5K (5 kilometers or 3.1 miles), 10K (10 kilometers or 6.2 miles), half marathon (21.1 kilometers or 13.1 miles), and marathon (42.2 kilometers or 26.2 miles). Understanding your pace at different distances helps with training plans, race strategy, and setting realistic performance goals. The calculator works for any distance, making it perfect for custom routes, track workouts, trail runs, or cycling rides.

Frequently Asked Questions

How do I calculate running pace?
To calculate running pace, divide your total time by your distance. For example, if you run 5 kilometers in 25 minutes, your pace is 5 minutes per kilometer. Enter your distance and time into this calculator to get instant pace calculations in both minutes per kilometer and minutes per mile.
What is a good running pace per mile?
A good running pace varies by fitness level and distance. For casual runners, 10-12 minutes per mile is common. Intermediate runners often maintain 8-10 minutes per mile. Advanced runners can sustain 6-8 minutes per mile or faster. Use this calculator to track your personal pace improvements over time.
How do you convert pace to speed?
To convert pace to speed, divide 60 by your pace in minutes per kilometer or mile. For example, a pace of 5 minutes per kilometer equals 12 km/h (60 ÷ 5 = 12). This calculator automatically converts between pace and speed in both metric and imperial units.
What distance should I enter for a 5K or marathon?
Common race distances are: 5K = 5 kilometers or 3.1 miles, 10K = 10 kilometers or 6.2 miles, Half Marathon = 21.1 kilometers or 13.1 miles, Marathon = 42.2 kilometers or 26.2 miles. Use the preset buttons in this calculator for quick access to these standard distances.
Can I use this calculator for cycling or swimming?
Yes! While designed for running, this pace and speed calculator works for any activity measured by distance and time. Enter your cycling distance and ride time, or swimming distance and swim time, to calculate your pace and speed for those activities.
Is pace or speed better for tracking running performance?
Pace (minutes per kilometer or mile) is preferred by most runners because it directly relates to race finish times. Speed (km/h or mph) is useful for comparing with other activities like cycling. This calculator shows both metrics so you can use whichever makes sense for your training goals.
