Age Grade Calculator
Score a race result as a percentage of the world best for your age and sex, so a masters runner and a 25-year-old can compare performances fairly.
Age grading expresses a result as a percentage of the world-best standard for that age, sex, and distance. We take your time, scale it by a WMA age factor (the fraction of peak performance typically retained at your age) to get an open-age equivalent, then compare it to the reference standard for the distance.
Rough bands: 90%+ world class, 80%+ national class, 70%+ regional class, 60%+ local class. The factors and reference standards here are close approximations of the official WMA tables, which are updated periodically — treat the result as accurate to a point or two, not a certified score.
Age grade ranks a single race against a table. It can’t tell you whether you left time on the course, how much fitness you’ve gained since, or what to run next. Two runners with the same age grade can need completely different training.
Vertical builds your personal performance curve from hundreds of your runs and updates it every time you train, so it knows your real level today, not just how one race scores against a static standard.
