Two record books, side by side

Age-grading levels the gap between ages and distances. Pick another runner to see two record books stacked against each other on the same numbers.

How it works

· Best age-graded percentage per runner, plus the gap in percentage points.
· Per-distance age-graded PRs side by side. Leader gets quiet emphasis, not a victory ribbon.
· Public profiles appear in suggestions; unlisted profiles resolve with the exact username. Private profiles 404.
· No account? Log your races to add your own column.
