Running Pace Calculator
Calculate your running pace, splits, and finish times for any distance. Convert between miles, kilometers, and meters.
What is Running Pace?
Running pace is the time it takes to cover a specific distance, typically expressed as minutes per mile or kilometer. Understanding your running pace is crucial for:
- Training for specific race distances
- Setting realistic race goals
- Planning your training runs
- Tracking your running progress
- Calculating split times for long-distance races
Common Race Distances
Our calculator includes preset distances for popular running events:
- Marathon (26.2 miles / 42.2 km)
- Half Marathon (13.1 miles / 21.1 km)
- 10K (6.2 miles / 10 km)
- 5K (3.1 miles / 5 km)
- 1 Mile (1.6 km)
- Ultra Marathons (50 miles, 100 miles)
How to Use the Calculator
Enter any two of the following values to calculate the third:
- Time: Your total running time
- Distance: The distance you plan to run
- Pace: Your target pace per mile/kilometer
You can also:
- Convert between different units (miles, kilometers, meters)
- Calculate split times for any distance
- Use preset common race distances
- Calculate pace for different segments of your run
Tips for Using Running Pace
Understanding and using running pace effectively can significantly improve your training and racing:
- Start with a comfortable pace and gradually increase it
- Use negative splits (faster second half) for optimal race performance
- Account for elevation changes and terrain in your pace calculations
- Consider weather conditions when planning your pace
- Use split times to adjust your pace during long runs
Training Applications
This calculator is useful for various training scenarios:
- Planning tempo runs and intervals
- Setting target paces for different training zones
- Calculating recovery paces between intervals
- Planning long run paces
- Setting race day pace targets

Using a pace calculator for 400m track workouts
Track workouts are a crucial part of many runners' training programs. Our calculator makes it easy to plan and execute 400m intervals:
- Calculate target times for 400m repeats
- Plan recovery periods between intervals
- Convert between 400m splits and mile pace
- Calculate total workout time and distance
- Plan progressive interval workouts
For example, if you want to run 400m repeats at 5:00 mile pace, you can quickly calculate that each 400m should take 1:15 (75 seconds).
