1. What is the Age Grade Calculator?

The Runner's World Age Grade Calculator Masters allows runners to compare their race times against age-specific standards. It provides a percentage that shows how your performance compares to the world record for your age group.

2. How Does the Calculator Work?

The calculator uses the age grade formula:

Where:

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

Explanation: The higher the percentage, the closer you are to the world record performance for your age group. 100% means you matched the world record.

3. Importance of Age Grading

Details: Age grading allows fair comparison of performances across different age groups and genders. It helps masters athletes track their performance relative to world standards as they age.

4. Using the Calculator

Tips: Enter the age standard time (available from official tables) and your actual race time, both in minutes. All values must be positive numbers.
