1. What is Age Grading?

Age grading allows runners to compare their race times with others of different ages and genders. It adjusts your performance based on age and gender-specific factors to determine how you compare to the world record for your age group.

2. How Does the Calculator Work?

The calculator uses the Age Grade formula:

Where:

• World Record Time — Current world record for the distance (minutes)
• Your Time — Your actual race time (minutes)
• Age Factor — Age-specific adjustment factor (dimensionless)

Explanation: The equation compares your performance to the world standard for your age group, with 100% representing world record level performance.

3. Importance of Age Grading

Details: Age grading provides a fair way to compare performances across different age groups and genders, helping athletes track their progress over time regardless of aging.

4. Using the Calculator

Tips: Enter the current world record time for 10K (in minutes), your actual 10K time (in minutes), and your age factor. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find world record times?
A: Official world records are maintained by World Athletics (formerly IAAF) for track events and various organizations for road races.

Q2: How is the age factor determined?
A: Age factors are based on statistical analysis of performance decline with age and vary by distance. They're published by organizations like World Masters Athletics.

Q3: What is a good age grade percentage?
A: Generally: 90%+ = world class; 80%+ = national class; 70%+ = regional class; 60%+ = local class.

Q4: Does this work for all distances?
A: The concept applies to all distances, but the age factors vary. Each distance has its own specific factors.

Q5: How often are age factors updated?
A: Factors are typically reviewed every 5-10 years based on new performance data.
