How to Use the Race Equivalency Calculator?

1. Select the Race Distance: Choose the distance for which you have a recent race time from the dropdown menu. Options include 1 Mile, 5K, 10K, Half Marathon, and Marathon.

2. Enter Your Time: Input your race time for the selected distance. Use the separate fields for hours, minutes, and seconds to ensure accuracy.

3. Calculate: Click the “Calculate Equivalent Performances” button to generate your results.The calculator will display a table showing estimated times for standard race distances (1 Mile, 5K, 10K, Half Marathon, and Marathon) based on your input.

The calculator uses a variation of Riegel’s formula, which assumes that performance declines predictably as race distance increases. This formula has been found to be reasonably accurate for most runners, especially over distances from 1 mile to the marathon.

By regularly using this Race Equivalency Calculator in conjunction with your training log and race results, you can gain valuable insights into your running performance and potential across various distances. This information can help you make informed decisions about your training focus and race selection, ultimately leading to improved performance and a more rewarding running experience.
