1. What is Reverse Age Grade Calculation?

The Reverse Age Grade Calculator determines the actual running time based on an age standard time and a percentage grade. This is useful for runners who know their age grade percentage and want to find out their actual time.

2. How Does the Calculator Work?

The calculator uses the reverse age grade formula:

Where:

• \( Age\ Standard \) — The standard time for a specific age group (minutes)
• \( Percentage \) — The age grade percentage achieved

Explanation: The formula reverses the standard age grade calculation to determine the actual running time that would result in a given percentage.

3. Importance of Age Grading in Running

Details: Age grading allows runners of different ages and genders to compare their performance fairly by accounting for the physiological effects of aging.

4. Using the Calculator

Tips: Enter the age standard time in minutes and your age grade percentage. Both values must be positive numbers.
