Age Grade Calculator
Score any running performance against the World Masters Athletics (WMA) age standards. It levels the field across age and sex so you can compare a 55-year-old's 10K with a 25-year-old's — fairly.
What the percentage means
Your age grade is the ratio of the age & sex world standard to your actual time. 100% means you ran a world-record-equivalent performance for your age group. Here's the scale serious runners use:
| Age grade | Level | What it means |
|---|---|---|
| 90–100% | World class | Elite international standard for your age. |
| 80–90% | National class | Among the best in your country for your age group. |
| 70–80% | Regional class | Strong club / regional-level runner. |
| 60–70% | Local class | A competitive, well-trained local runner. |
| Below 60% | Recreational | Solid recreational fitness — a great place to build from. |
Why age grading matters
Raw finish times reward youth. Age grading uses the WMA standards — the same data Parkrun and most race results use — to express performance as a percentage of the best possible time for someone of your exact age and sex. It's the fairest way to track your own progress as you get older, and to compare yourself across an age-group field.
Note: results use the published WMA road standards and age factors and are accurate to within a fraction of a percent for typical distances. Official race timing may use a specific WMA table edition.
Is a 60% age grade good?
Yes — 60% reflects a well-trained recreational runner. Most casual runners sit in the 45–60% range, so crossing 60% is a real milestone. 70%+ marks regionally competitive runners.
How is age grade calculated?
Age grade % = (age-and-sex standard time ÷ your time) × 100. The standard is the open-class world standard divided by an age factor that reflects the natural decline in performance with age.
