Running Pace Calculator
Calculate your running pace per km and per mile from distance and time.
Pace is the runner's core metric — minutes per kilometer or mile — and it's the number that turns a distance and a goal time into a plan. Knowing that a sub-2-hour half marathon means holding 5:41 per kilometer changes how you train and how you run the race itself.
Enter a distance and the time you ran (or want to run) it in, and this calculator gives your pace per km and per mile, plus your average speed. Use it to check a training run, work out the pace needed for a target finish time, or convert between the two pace units when following an international plan.
