1. What is Age Grading in Running?

Age grading allows runners of different ages and genders to compare their performance. It adjusts your actual time to what it would be if you were in your prime running years (typically 20-35).

2. How Does the Calculator Work?

The calculator uses the age grading formula:

Where:

• \( Time \) — Your actual 10-mile run time in minutes
• \( Age Factor \) — Adjustment factor based on your age and gender

Explanation: The age factor accounts for typical performance changes with age, allowing fair comparison across different age groups.

3. Importance of Age Grading

Details: Age grading helps motivate older runners by showing how their performance compares to their younger selves and others. It's widely used in masters running competitions.

4. Using the Calculator

Tips: Enter your 10-mile run time in minutes, your age in years, and select your gender. The calculator will show your age-graded time.
