Running Calculator: Pace, Race Predictor, Splits
Pace Calculator
The running pace calculator is the main function of the application. Its a multi purpose tool for runners that instantly updates distance, speed or time as needed. Enter a race distance and target time to check the pace needed. Convert between pace per mile, pace per kilometre or pace per 400m. Standard race distances are available for selection or alternatively enter your own distance. Speed conversions can be useful for runners who run on a treadmill. Instead of minutes per mile or minutes per kilometre you can enter your running speed in kph, mph or m/s.
Cadence calculator shows you your stride length at a given cadence. You can update either stride length or cadence to see how the other is affected. For example, if I run a 5k in 20 minutes at 180 steps per minute how many meters am I covering with each stride. It's generally advised that 180 steps per minute is a good aim for the average runner. Elite 5k runners can cover over 2 meters per stride!
Age Grading is available in the pace calculator for 5k, 10k, half marathon and marathon. This compares your time over the distance to the world record time based on age and gender. It's a nice way to compare your result to a runner of another gender, different age category, or just running a different race distance.
Elevation Calculator let's you calculate the gradient of a hill or the amount of elevation that you will gain running at a particular gradient. For example if I run for 6 miles on a treadmill at 4% how many meters have I gained?
Body Mass Index – (BMI) is a guide to the healthy weight range for your height used by the government and health professionals. It might not be applicable to every body type but its a good starting point! Enter your height and weight in lbs or kilograms to get your BMI score and a useful BMI reference guide. You can set a preference to show or hide the BMI section from the pace calculator if you wish.
Race Predictor
If you have a race time and you would like to get an estimate of what you might be running in another race you can use the race time predictor. Here you enter a time for any of the provided race distances and all other distances instantly update with your predicted finish time at that distance. Example usage as a marathon time predictor: I run my local 5k parkrun in 25 minutes. How long do you think it will take me to run a marathon? Race predictions are available for 400m, 800m, 1k, 1500m, 1 mile, 3k, 5k, 5 miles, 10k, 10 miles, half marathon and marathon.
Running Splits
Finally you can use Running Calculator to plan your race strategy using the running splits screen. Pick a distance from 800m, 1500m, 5k, 10k, half marathon, marathon or a custom distance in miles or kilometres, enter your finish time and we'll display the splits that you will need to run for that time. You can configure whether you would like the splits listed per kilometre, per mile, per 400m, per 5 kilometres or per 5 miles. Why not try it out at your next parkrun or race and see how you get on?
These functions should prove useful for 5k training, half marathon training and marathon training. If there are other functions that Running Calculator should handle then please get in touch.

Amazing app! Easy to use. Really wish I found it earlier. Fantastic tool for any runner.
Love it. Very few can have mixed units for distance and pace on one page, eg marathon distance in miles and pace in mins per km. I also like the auto calculation as you type, no need to waste screen space with many buttons to calculate the measure you want. It might seem simple but that's what makes good product; user friendly.
horrible. I want to convert a 10:30 mile into mph. cant do it. the more you use this the less you'll like it.. (edit) yes. it is possible to get your pace but as you type 10:30 and set it to Miles it automatically assumes the 10:30 km (default is km) was correct and changes your input to 16:xx mi... meaning... you get to re enter the one bit of correct information you had in this stupid app. really poorly designed.
I am running endurance coach and use this when talking to my athletes andplanning their sessions. Simple, effective and stable. Best running calculator app I have used.
Great, works really well. Ideal for working out your pace from time and distance as well as converting km to miles or vice versa.
Disappointed with ads being added. had previously laid for this, and did not recall having ads. I had paid in good faith and now ads are intruding. will keep, but not happy.
Fast and very useful for calculating my runs. I love that it will do kilometer / mile pace conversions! Highly recommended.
I would rate it with 1 but I searched for pace calculator, hoping I woul be able to calculate a distance based on pace and time. So it's my fault but it is easy to add this functionality: to be able to calculate pace, or distance or time
Perfect for identifying ideal pace to achieve goal race times, converting miles and kilometer pace etc....My go to app for anything pace related.
This app is perfect, put your time or pace and distance and it works everything else out for you. Great companion app to Strava to get distance times
Amazing app very simple to use and shows your realistic targets according to current pbs or a pace guide if you are chasing a time
It helps me to make race prediction so easy. Best apps for running. Thanks for making this one free apps.
Purchased this awhile ago but only just started using it. So far, very pleased. Will update review and star rating in a few weeks time when I've given the app a proper whirl.
Exactly what every runner needs. Calculate the speed or pace in an very easy way.
It needs to explain usage. What are the yellow #s? Also, it doesn't show age adjusted times, just percentanges.
Great for any runner new ones in particular will benefit from the prediction tool for pacing in new distances
Simple and easy to use. Has key running metrics.
Just what I need. A simple predictor for running split times. Predictions very true.
good app be nice if it remembers last input when closed or option to save it.
easy to use and all the info I needed. Would recommend.
Works as intended. Practical and intuitive.
Easy to use. New runner to experienced data keeper
Does everything I'd want, very simple. Exactly what I need.
Simple to use and very useful for runners
Brilliant and really useful. Easy to usr
I enjoy calculating performance on this app, simple and gets the job done
Super app. Use it always. No bugs.
Great app to use when you dont have a Garmin, or if you need to know a pace.
Very useful app for runners. I love the interface and functionality. Please consider adding an option in the preferences to change the default tab when you open the app. I find myself using the predictor tab more than the calculator tab. Kudos to the dev! 😃
