Running Calculator: Pace, Race Predictor, Splits

Running app with pace calculator, accurate race predictor and running 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.
