1. What is Age Grade?

Age grade is a percentage that allows athletes to compare their performance against the world record time for their age and gender. It provides a way to compare performances across different age groups.

2. How Does the Calculator Work?

The calculator uses the age grade formula:

Where:

• Age standard — World record time for your age and gender (minutes)
• Time — Your actual time (minutes)

Explanation: The equation calculates what percentage of the world record time you achieved. Higher percentages indicate better performance.

3. Importance of Age Grade Calculation

Details: Age grading allows fair comparison between runners of different ages and genders. It helps athletes track their performance improvements over time regardless of aging.

4. Using the Calculator

Tips: Enter the age standard time (world record for your age/gender) and your actual time in minutes. Both values must be positive numbers.
