What Is a PR in Track? PR vs PB vs SB

August 10, 2026 · 7 min read

PR stands for personal record: your best ever mark in a given event. That is the whole definition, and if that is all you needed, you are done.

The reason people keep searching it is the part underneath. Which marks actually count as a PR, and which ones you are quietly not allowed to claim.

PR, PB and SB

PR, personal record. The American term. Your lifetime best in that event.

PB, personal best. The international term for exactly the same thing. British, Australian and World Athletics results say PB. American high school and college results say PR. There is no difference in meaning, and nobody will correct you.

SB, season best. Your best mark this season. Different concept, frequently confused with the other two. If your PR is from last spring and your SB is two tenths slower, both numbers are true and they tell a coach different things.

PRs are per event, and more per-event than people think

Your 100m PR and your 200m PR are separate. Obvious.

Less obvious, and where arguments start:

Indoor and outdoor are tracked separately. Indoor tracks are usually 200m with tight turns, so indoor marks are generally slower in the sprints and the 400m. Comparing your indoor 400m to your outdoor 400m is comparing two different events, which is why results systems keep two lists. See what actually changes between the seasons.

The 1600m and the mile are not the same distance. The mile is about nine metres longer. Some meets run one, some the other, and converting between them is a real conversion rather than a rounding.

Hand timed and FAT are not the same scale. More on this below, because it is the one that actually costs people credibility.

Does a wind-aided mark count as a PR?

This is the most common edge case, and the honest answer is: it depends who is asking.

If the tailwind exceeded 2.0 metres per second, the mark is wind-aided, written with a w, as in 11.32w. The result of the race stands. You beat the people you beat. But the mark is not record-legal, so it cannot be a state record, a meet record, or a nationally ranked mark.

Convention among people who read results for a living: a wind-aided mark is not your PR. Most athletes keep it as a separate line, sometimes described as a wind-aided best. Claiming 11.32 flat when it was 11.32w is the kind of thing that gets noticed immediately, because the w is in the official results and the coach will look.

The rules for which events even take a wind reading, and why the limit sits at exactly 2.0, are in wind-legal marks explained.

Does a hand time count as a PR?

For your own motivation, of course. For recruiting, treat it as a different currency.

A stopwatch starts late, because a human is reacting to the gun, and stops roughly on time, because a human can anticipate the finish. The result is systematically fast by around a quarter of a second. That is why the conversion exists, and why a hand-timed 11.2 is treated as an 11.54 rather than as an 11.2.

So you can hold a hand-timed PR and a FAT PR at the same time, and they are not comparable numbers. Say which is which, every time. The full mechanism, including the rounding step almost everyone gets wrong, is in hand time or FAT.

What makes a PR real to a coach

Four things, and they are the same four every time:

1. A sanctioned meet. Practice does not count, however honestly timed.
2. A timing method stated. FAT or hand.
3. A wind reading, for the 100m, 200m, both short hurdles, long jump and triple jump.
4. Results a coach can find. A meet name and a date they can look up.

A mark with all four is evidence. A mark missing two of them is a claim, and coaches receive hundreds of claims a week.

The practical version

Keep your marks honest and specific, and you will never have an awkward conversation:

• 11.54 FAT, wind +1.2, outdoor. That is a PR.
• 11.32w FAT, wind +3.1, outdoor. That is a wind-aided best, not a PR.
• 11.2 hand, converts to 11.54. That is a hand-timed mark, and say so.
• 7.21 FAT, indoor 60m. Different event, own PR.

This is exactly why TrackReels requires the event, mark, date, wind and timing method at upload rather than letting them live in a caption. PRs are detected on the server from those fields, so a PR badge is something the data says rather than something an athlete awards themselves, and wind-illegal marks are labelled rather than counted. You can see how that looks on any event leaderboard.
