1. What is Age-grading?

Age-grading is a method to compare running performances across different ages and genders by adjusting times according to age-specific factors. It allows runners to see how their performance compares to world-class standards for their age group.

2. How Does the Calculator Work?

The calculator uses the age-grading formula:

Where:

• World record time — Current world record for 5k (minutes)
• Time — Your 5k time (minutes)
• Age factor — Multiplier based on your age and gender

Explanation: The equation compares your performance to the world record standard, adjusted for your age.

3. Importance of Age-grading

Details: Age-grading provides a fair way to compare performances across different age groups and helps runners track their performance relative to their potential as they age.

4. Using the Calculator

Tips: Enter the current world record time for 5k in minutes, your 5k time in minutes, and your age factor. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find age factors?
A: Age factors are published by World Masters Athletics and other running organizations, typically in age-grading tables.

Q2: What is a good age-graded percentage?
A: 60% is local class, 70% is regional class, 80% is national class, 90% is world class, and 100% is world record level.

Q3: Does this work for other distances?
A: Yes, but you need the appropriate world record and age factor for each specific distance.

Q4: How often do age factors change?
A: Age factors are updated periodically (every 5-10 years) based on new research and performance data.

Q5: Can I use this for training planning?
A: Yes, age-grading can help set appropriate training goals and track progress relative to your age group.
