1. What is Age Grading?

Age grading allows runners to compare their race performances against others of different ages and genders. It provides a percentage score where 100% represents the world record level for your age and gender.

2. How Does the Calculator Work?

The calculator uses the age grade formula:

Where:

• \( Age\ Standard \) — The world record time for your age and gender (minutes)
• \( Time \) — Your actual race time (minutes)

Explanation: The formula compares your performance to the age-standard world record, giving a percentage that indicates how close you are to that standard.

3. Importance of Age Grading

Details: Age grading helps runners track their performance over time, compare with others fairly, and set realistic goals based on age and gender.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Where can I find age standard times?
A: Age standard times are published by running organizations like WMA (World Masters Athletics) or Good Run Guide.

Q2: What is a good age grade percentage?
A: Over 90% is world class, 80-90% is national class, 70-80% is regional class, and 60-70% is local class.

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

Q4: How does age affect running performance?
A: Performance typically peaks in the 20s-30s and declines gradually with age, but age grading accounts for this.

Q5: Can I use this for walking events?
A: Yes, if you have the appropriate age standard times for walking events.
