Age-Grade Calculator

The Age-Grading Calculator is one of the most useful tools for understanding your running performance beyond raw finish times. It allows you to compare results fairly across ages and genders, giving you a clear picture of how your efforts stack up against others and against world-class performances.

What is Age-Grading in Running?

Age-grading converts your race time into a percentage that reflects how close it is to the world record for your age and sex. A higher percentage means your performance is closer to the best in the world for someone like you. For example, an 80% result is considered national-class, while 90% and above indicates world-class ability.

This metric helps you compare fairly with runners of different ages, track your progress over time, and set meaningful goals. It also gives you a benchmark to aim for when training or using other tools like the pace calculator or running plan generator.

How the Age-Grading Calculator Works

1. Enter your age: This ensures the calculation uses the correct record standards for your category.
2. Select your sex: Times are adjusted against the appropriate gender benchmarks.
3. Choose race distance: From 5K to marathon, the calculator adapts to your chosen event.
4. Input your finish time: Use hours, minutes, and seconds in standard race format.
5. View your percentage: The calculator returns your age-graded score and classifies your performance level.

The calculator can also predict how you might perform at other race distances based on your age-grading percentage, helping you set smart targets for your next event.

Why Use Age-Grading?

For everyday runners, age-grading adds context to your achievements. A 50-year-old runner completing a 10K in 45 minutes is very different to a 20-year-old doing the same, and age-grading captures that distinction. It’s also a great way to measure your progress as you move through different stages of life, keeping motivation high and goals realistic.
