1. What is Age Graded Running?

Age grading is a method used in running to compare the quality of performances across different age groups. It allows runners of different ages and genders to compare their race performances against each other and against standard performances for their age and gender.

2. How Does the Calculator Work?

The calculator uses the age grading formula:

Where:

• \( world\_record\_age \) — World record time for your age group (minutes)
• \( actual\_time \) — Your actual race time (minutes)

Explanation: The equation calculates what percentage of the world record time you achieved in your race.

3. Importance of Age Grading

Details: Age grading helps runners track their performance as they age, set realistic goals, and compare performances with runners of different ages. It's particularly useful for masters athletes (over 40).

4. Using the Calculator

Tips: Enter the world record time for your age group and your actual race time, both in minutes. All values must be positive numbers.
