# The bib means nothing until somebody else keeps the stub

> A race bib is assigned by a database and means nothing to anyone — until a stranger tears off the stub at the finish and keeps it.

4417, very large, in black. HARBOUR ROAD 10 in small red type above it. Four pin holes, one at
each corner, where it pinned to a shirt for a few hours. A perforated stub across the foot,
carrying the same number.

Nobody chose 4417. A database did, in the week before the race, and for most of the morning it
means nothing at all.

## What is a race number actually for?

Identification — and for most of the morning, nothing more than that.

A number ties a runner to a name in a database, so results can be posted afterwards and so a
marshal at a junction or a volunteer at a water station knows who's in the race and who's a
spectator. It's handed out in registration order or by a draw, for reasons that have nothing to do
with the person wearing it. 4417 doesn't say anything about speed, or effort, or the morning ahead
of it. It's a lookup key in a large black font.

## Why does the bib get torn in two at the finish?

Because the stub is the part of the system built to leave the runner's body and end up in
somebody else's hands.

The main panel stays pinned to the shirt for the whole distance. The stub across the foot is
perforated so it separates cleanly — a volunteer collects it, or a reader scans it, and from that
moment there are two copies of 4417 in the world where a minute earlier there was one. Unlike
[the hole punched in an orienteering control card](/stories/orienteering-control-card),
which proves exactly where somebody stood, a bib's stub proves something simpler: that a specific
number crossed a specific line, with no battery and no signal involved.

## What makes a good one to have printed?

Whether the number and the event name came from an actual morning, or were built to look like they
could have.

HARBOUR ROAD 10 above 4417 reads as a specific record if 4417 is the number that was genuinely
pinned to somebody's chest that day. An invented race works on different terms — nobody's claiming
a result happened, so the pin holes and the tear-off stub carry the weight instead, because that
structure is what tells a stranger what kind of object this is copying, independent of whether the
event itself ever ran.

## Can a real race's name go on a shirt?

If a specific morning is the point, get the organiser's permission first — race names are licensed
routinely, and most series will grant it for a one-off shirt without much friction.

An organiser owns the event's name, the way any event owns its own branding, and licenses it out
for merchandise already. Where the point isn't a specific real event, an invented name does the job
at least as well: a real bib belongs to one entrant and one result; an invented one belongs
entirely to whoever's wearing it, with no course record and no sponsor attached to argue about.

## Does this work for something other than a 10K?

Anywhere a number gets handed out before a result exists.

A fun run, a park run, a charity walk, one leg of a triathlon — wherever registration produces a
number ahead of the event, a bib exists in some form, even where the paper looks slightly
different. Pin holes and a tear-off stub aren't particular to running; they belong to any race that
has to identify its entrants without a working connection at the finish line, the same reason
[a fixture card gets issued before a ball is kicked](/stories/sunday-league-fixture-card).

## Isn't a number assigned by a database a strange thing to want on a shirt?

Not really — that's closer to why it gets kept rather than binned.

Nobody chose 4417, which is exactly why it can't be made to mean something it doesn't. A medal
tells a stranger the wearer achieved something recognisable. A bib number tells a stranger nothing
and tells the runner everything — proof of a specific morning rather than a claim about ability —
and [a pace band works from that same distinction between a plan and a result](/stories/marathon-pace-band):
one describes what was meant to happen, the other survives as what did.

## Does a bib print well?

Yes — flat black on white or bone, with one spot colour, is close to the paper original already.

The number should stay the largest thing on the shirt; shrink it to leave room for other detail and
the print loses the object it's copying. Keep the pin holes small and render the perforation on the
stub as a genuinely broken line rather than an even dashed rule — a slightly irregular gap reads as
torn, a regular one reads as drawn. One red for the event name carries enough weight on its own;
adding more colour starts competing with the number above it.

## How do I get one made?

Describe your bib at [JustOG](/) — the number, the event name, and whether the stub is still
attached. Pick a direction, drag the crop frame, see it composited on the real garment, and it's
made to order and shipped.

Designs other people have published are in the [shop](/shop).

Somewhere there's a stub with 4417 on it, kept by a stranger the runner didn't speak to.
