How long will it take you to walk or run a certain distance, and what is your speed and pace? You can use this online calculator to find any of those three things - pace, distance, or finish time, by entering two of them. For distance, you can enter a number or select a distance such as 5K, 10K, half marathon or marathon.

Pace or Speed Calculation

Your pace is your speed in minutes per mile or minutes per kilometer.

This is the time it would take you to walk or run one mile or one kilometer. You often need to know your pace when you enter a large race. The race organizers use it to assign you to a start corral with others who will be racing at a similar pace

To calculate your pace or speed, you will need to know the distance you have walked or run and the time it took you to do so. Enter those into the calculator to find your pace.

  • Pace = Distance / Time

The pace calculator can be a good check on what your GPS app or wearable is giving you as a speed or pace. Often these can be inaccurate and you don't want to think you are faster than you actually are.

Distance Calculation

If you know your pace and how much time you will be walking or running, you can calculate how far you should go in that time. This can be useful if you have a set amount of time for a workout and want to see how far you could go in that time.

To calculate distance if you know your pace and time, enter pace and time into the calculator to get the distance in either kilometers or miles. Again, the accuracy of this prediction depends on having an accurate pace.

  • Distance = Pace / Time

Finish Time Calculation

How long will it take you to finish a 5K, 10K, half marathon or marathon?

This is a critical piece of knowledge to have before you register for a race. If you are a walker or slow runner, you have to be sure that you can finish in under the course time cutoff. You may also want to compare your finish time with lists of winners to see if you might qualify for a trophy for your age group.

To calculate your finish time, you will need to know your pace in minutes per mile or minutes per kilometer, and the distance of the course. Enter those into the calculator.

  • Finish Time = Pace / Distance

Be sure you are checking your pace in more than one way, as a GPS-based speed may be inaccurate. Doing a timed mile or a timed kilometer can be a better way to find an accurate pace. Otherwise, your finish time will also be inaccurate.

Predicting Finish Time for Longer Races

While you may be able to time yourself over a mile or kilometer and use that to predict your time for a 5K or 10K race, you probably won't be able to maintain the same speed over a half marathon or marathon. Use these resources to predict longer race finish times.
