What this result means
People search “running percentile” expecting a rank in a population. This lab does not have a population. It has interpolated WMA 2015 factors and published band cut-points (90, 80, 70, 60). The honest product is that mapping, labelled clearly.
If you want the raw percent and age-graded time, use the age-grading calculator. If you want a one-line “how good,” use How Good Is My Running Time? This page exists so the percentile query lands on an honest explanation instead of a fake rank.
A 70% age grade is labelled regional class here. That does not mean you finished in the 70th percentile of your age group at last weekend’s 10K. A 90% is labelled world class as a convention, not a World Athletics ranking.
Enter a 5K, 10K, half, or marathon. Other distances are out of scope, same as the other WMA tools.
Calculation method
Same percent as age grading. Bands: ≥90 world class, ≥80 national, ≥70 regional, ≥60 local, else recreational. Cite WMA 2015 interpolated subset.
No census, no race-result scrape, no age-group rank.
Do not quote this as a percentile in a field of N runners. It is a table band. Age grading still ignores downhill and wind.
Frequently asked questions
What percentile is my 5K?
This site cannot rank you in a real field. It maps WMA age grade to performance bands and says so.
Is 70% the 70th percentile?
No. 70% is an age-grade percentage against an elite standard, labelled regional class by convention.
Where do the bands come from?
The same 90/80/70/60 cut-points used on How Good Is My Running Time?
