How to read this
The shorthand most people use is 60% local class, 70% regional, 80% national and 90% world class. 100% is the world best for the distance, adjusted for age. The tables are single-year, so the target moves a little every birthday rather than jumping every five years like a race age group does.
Age grading corrects for age and sex only. A downhill course or a tailwind still grades the same as a flat, calm day. The methodology page has the formula and the source tables.
