1. What is Age Graded Percentage?

The Age Graded Percentage is a method used to compare race performances across different age groups. It allows athletes of different ages to compare their performances on an equal basis by accounting for age-related performance differences.

2. How Does the Calculator Work?

The calculator uses the Age Graded Percentage formula:

Where:

• \( \text{Age standard} \) — The standard time for a specific age group (minutes)
• \( \text{Time} \) — The actual time achieved by the athlete (minutes)

Explanation: The equation compares an athlete's performance to the world record performance for their age group, expressed as a percentage.

3. Importance of Age Grading

Details: Age grading allows fair comparison between runners of different ages and genders. A percentage of 100% represents a world record level performance for that age group.

4. Using the Calculator

Tips: Enter the age standard time (in minutes) for your age group and your actual race time (in minutes). Both values must be positive numbers.

Q3: Does this work for all race distances?
A: Yes, as long as you have the appropriate age standard times for your specific race distance.

Q4: How often are age standards updated?
A: Typically every 5-10 years to reflect changes in world record performances.

Q5: Can I use this for team competitions?
A: Yes, some competitions use the sum of age graded percentages from team members to determine team rankings.
