How this works
Age grading compares your road performance with an age- and category-specific reference standard for the selected distance. It is a comparison tool, not a physiological measurement or a perfect normalization of every runner.
Age-Adjusted Performance is a comparison value derived from the same reference model; it does not change your recorded result.
Methodology and reference dataset
