Records only count in races

Personal records can be broken at any age.

Track every race you run. Watch your age-graded percentages climb as your absolute times do, or hold steady as the years move you up a bracket.

Three measurements.
Nothing else worth keeping.

We’re not a fitness feed. Not a coach. Not a starter template. A record book for runners who’d rather see the stopwatch than a kudos count.

Your time, as a percentage of the world best, adjusted for your age.

Two grading systems: WMA 2023 (the standard, track and road) and Alan Jones 2025 (road only, sharper at sub-elite times). The same 5K from a 22-year-old and a 67-year-old produces two very different percentages.

Every race ranked by what it’s worth, not by the stopwatch.

Type races in, or pull them from Strava. The PR you set at 45 stays the PR even when the 1:24:18 from your 20s is out of reach. Records can be broken at any age; the percentage is the metric that doesn’t harden.
