Purpose: Calculate your running/walking pace per kilometre and mile, plus average speed, from the distance covered and time taken.
Pace Calculator
The Pace Calculator links the three variables every runner cares about - pace, distance, and time - so you can find any one from the other two and plan your race.
Pace, time, or distance
Enter any two and it solves for the third: work out your pace per kilometre or mile from a finish time, predict a marathon time from your training pace, or find how far you can go in a set time. Pace is simply time divided by distance, and speed is its inverse - the calculator handles the unit juggling for you.
Plan your race
Use it to set target splits for a 5K, 10K, half, or full marathon, and to convert between min/km and min/mile. Knowing the exact pace you need to hold takes the guesswork out of race day and helps you avoid starting too fast - the classic rookie mistake.
Frequently Asked Questions
How do I calculate my running pace?
Divide your time by the distance covered. For example, 25 minutes over 5 km is a pace of 5:00 per km.
Can it predict my marathon finish time?
Yes. Enter your target pace and the marathon distance to estimate a finish time, or work backwards from a goal time to the pace you need.
Does it convert between km and miles?
Yes. It handles both min/km and min/mile, so you can switch between metric and imperial pacing.
What is the difference between pace and speed?
Pace is time per unit distance (min/km); speed is distance per unit time (km/h). They are inverses of each other.
