What this percentile really means
Unlike calculators based on formulas, this tool queries real data: the personal bests of 800,000+ athletes with a World Athletics profile. Your percentile tells you exactly where you would sit among them.
Keep in mind the population is competitive athletes, not the general public — beating 50% of this database already puts you far above the average runner. Data updates daily with new results.
Am I fast? — FAQ
Against the outdoor personal bests of more than 800,000 athletes who have a World Athletics profile — from club runners to Olympic champions. It is a competitive population: beating 50% of it is already a strong result.
Yes. 11.00 beats roughly half of the men's 100m personal bests in our database of registered athletes — and virtually everyone outside organized athletics.
The comparison pool only contains athletes good enough to appear in World Athletics results. The average person is not in this database, so percentiles read tougher than against the general public.
19 events: sprints (100m to 400m), middle and long distance (800m to 10,000m), road (half marathon, marathon), the four jumps and the four throws.
The database syncs daily with new competition results, so your percentile reflects an up-to-date snapshot of world athletics.
