10K Age-Grading Calculator
Use this 10K age-grading calculator to see how a road 10K performance compares after age and gender are considered. It is built for single-run comparisons, not official rankings.

Age-adjusted equivalent45:58
A 57-year-old male running 10K in 55:00 is age-adjusted to approximately 45:58. That means the performance is comparable to an open-age runner completing 10K in about 45:58.

Why 10K age grading is useful
The 10K is a good distance for age-group comparison because it mixes speed, endurance and pacing discipline. Many runners know what a 45-minute, 55-minute or 60-minute 10K feels like, but the same raw time can mean different things at different ages.
TruePace Run uses sourced 2025 road-running standards and shows the source near the result. Treat the output as useful context rather than a race certificate.
Good uses for this page
- Comparing two club runners of different ages.
- Judging whether a 10K goal is realistic for your current age group.
- Adding context to a slower raw time after years away from racing.

FAQ
10K calculator FAQs
Quick answers for using this distance-specific calculator sensibly.
Is a 10K age-graded result an official ranking?
No. It is a useful estimate based on sourced standards, not an official ranking from a federation, race organiser or timing provider.
Why is 10K useful for age grading?
The 10K combines speed and endurance, so it is a practical benchmark for comparing age-group performances without relying only on raw pace.
Can I change the distance on this page?
Yes. The calculator opens with 10K selected, but you can switch to 5K, half marathon or marathon if you want to compare another result.
