1. What is Running Age Grade?

The Age Grade is a percentage that allows runners to compare their race times to the world record time for their age and gender. It provides a way to compare performances across different ages and distances.

2. How Does the Calculator Work?

The calculator uses the Age Grade formula:

Where:

• \( best\_time\_age \) — World record time for your age/gender/distance (minutes)
• \( actual\_time \) — Your actual race time (minutes)

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

3. Importance of Age Grading

Details: Age grading allows fair comparison between runners of different ages and genders. It helps track performance improvements over time and motivates runners by showing how they compare to world standards.

4. Using the Calculator

Tips: Enter the world record time for your age/gender/distance and your actual race time in minutes. Both values must be greater than zero.
