1. What is the USATF Age Grade Calculator?

The USATF Age Grade Calculator allows masters athletes to compare their performance against the standard for their age group. It provides a percentage that shows how close you are to the world-record performance for your age.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: A higher percentage means you're closer to the world record performance for your age group. 100% would mean you matched the world record.

3. Importance of Age Grading

Details: Age grading allows fair comparison between runners of different ages and genders. It helps masters athletes track their performance relative to their age peers and world standards.

4. Using the Calculator

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