Pace Calculator
Calculate running, walking, or cycling pace per mile and kilometer. Also compute time from pace and distance, or distance from pace and time.
About this Calculator
Calculate running, walking, or cycling pace per mile and kilometer. Also compute time from pace and distance, or distance from pace and time.
Formula & Calculations
Formula
Pace = Time ÷ Distance | Time = Pace × Distance | Distance = Time ÷ PaceWhere:
- Pace=Time per unit distance (min/km or min/mile)
- Time=Total elapsed time in minutes
- Distance=Total distance in kilometers or miles
Assumptions
- Assumes a constant pace throughout the entire distance.
- Conversions between miles and kilometers use 1 mile = 1.609344 km.
- Time inputs are converted to total seconds for precision before calculation.
Calculation Examples
Example 1
25 minutes ÷ 5 km = 5 minutes per km. Converted to miles: 5 × 1.609 = 8.045 min/mile ≈ 8:03 min/mile.
Example 2
6 min/km × 42.195 km = 253.17 minutes = 4 hours, 13 minutes, 10 seconds for a full marathon.
Frequently Asked Questions
What is a good running pace?
A 'good' pace varies by fitness level, age, and distance. For a 5K, beginner runners typically pace 7:00-8:30 min/km, intermediate runners 5:30-7:00 min/km, and advanced runners 3:30-5:00 min/km. Use this calculator to track your personal progress over time.
How do I use pace to predict race times?
Once you know your pace for a given distance, multiply it by the target race distance to estimate your finish time. For example, if you run 5K at 5:30 min/km, a 10K would be approximately 55 minutes. Note that pace typically slows slightly as distance increases.
Why does this calculator show both min/km and min/mile?
Pace is commonly expressed in min/km in most countries and in min/mile in the US and UK. Providing both helps you compare your pace across different tracking apps, race results, and training plans.
