Running Calculator: Pace, Race 4.7

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

The running pace calculator is the primary feature of the application. It is a versatile tool for runners that instantaneously updates distance, speed, or time as required. Input a race distance and target time to determine the necessary pace. You can convert between pace per mile, pace per kilometer, or pace per 400m. Choose from standard race distances or input your own. Speed conversions are helpful for treadmill runners; you can input your running speed in kph, mph, or m/s instead of minutes per mile or minutes per kilometer.

The cadence calculator displays your stride length at a given cadence. Adjust either stride length or cadence to see how the other is impacted. For instance, if you complete a 5k in 20 minutes at 180 steps per minute, how many meters are you covering with each stride? The average runner is typically advised to aim for 180 steps per minute. Elite 5k runners can achieve over 2 meters per stride!

Age Grading is available in the pace calculator for 5k, 10k, half marathon, and marathon distances. This feature compares your time over the distance to the world record time based on age and gender, offering a way to benchmark your performance against runners of different ages, genders, or distances.

The Elevation Calculator allows you to determine hill gradients or the amount of elevation gained when running on a specific gradient. For example, if you run 6 miles on a treadmill at a 4% incline, how many meters have you ascended?

Body Mass Index (BMI) serves as a guide to the healthy weight range for your height, commonly used by government and health professionals. While it may not apply to all body types, it provides a good starting point. Input your height and weight in pounds or kilograms to calculate your BMI score and reference guide. You have the option to show or hide the BMI section from the pace calculator.

The race predictor feature enables you to estimate your performance in one race based on your time from another race. Input a time for any provided race distance, and your predicted finish times for other distances will instantly update. For example, to predict marathon time based on a local 5k parkrun time of 25 minutes.

Race predictions are available for various distances including 400m, 800m, 1k, 1500m, 1 mile, 3k, 5k, 5 miles, 10k, 10 miles, half marathon, and marathon.

Lastly, utilize the Running Calculator's running splits screen to strategize your race pacing. Select a distance from options such as 800m, 1500m, 5k, 10k, half marathon, marathon, or a custom distance in miles or kilometers. Input your finish time to view the required splits for that time frame. Choose how you'd like the splits displayed: per kilometer, mile, 400m, 5 kilometers, or 5 miles. Test this feature at your next parkrun or race to assess its effectiveness.

These functionalities will be valuable for training purposes in preparation for a 5k, half marathon, or marathon. If there are additional functions that users believe Running Calculator should include, they are encouraged to provide feedback.
