# Laps & primes

> Lap counting, target lap counts, voiding a lap, and awarding primes.

For criteriums, short track, and any race scored by laps.

## Turning lap mode on

**Timer setup → Races**. Pick the race — or tick several, or **All races** — then
tick **Count laps** and optionally set which lap finishes riders.

Only what you change is written, so setting a lap count across five categories
won't disturb anything else they each have configured.

| Setting                   | Effect                                              |
| ------------------------- | --------------------------------------------------- |
| Lap mode on, no target    | Laps accumulate. You decide when riders are done    |
| Lap mode on, target of 20 | A rider is automatically finished on their 20th lap |

Each race carries its own setting, so a criterium and a road race in the same
event don't have to agree.

## Timing it

Same as any other race — type the bib each time that rider crosses. The screen
counts their laps for you and shows each rider's lap total and best lap.

The recording point button reads **Lap** rather than **Finish** once lap mode is
on, so there's no ambiguity about what Enter does.

> !!-IMAGE-NEEDED-!! — A lap-mode race in progress, showing per-rider lap counts and best lap.

### In a shared chute

Lap races work on the [combined finish](/timing/formats/combined-finish) screen
too. The race sheet grows a **Lap** column (`3/5`) and a **Lap times** column
listing every lap, and a crossing recorded for a lap-race rider counts as a lap.

Any timing point out on course lists **every pass** as well, so if a marshal at
the top of the climb sees the field on all eight laps, you get eight times per
rider — which is where you find the lap somebody lost two minutes.

What a crossing means is read from the **rider's race**, so a criterium counting
laps and a road race taking finishes can share one chute and one operator
without anyone flipping a control between them. Riders are finished on the lap
that hits the target, and the confirmation says so.

## Voiding a lap

A rider takes a lap they shouldn't have counted — a mechanical, a crash, a
penalty, a wheel change. You need to remove that one lap without removing the
rider.

From the rider's row menu, choose **Void a lap**, pick the lap, choose a reason,
and add a note if it needs explaining.

What happens:

* The lap comes off their count.
* Their best lap recalculates.
* If that lap was the one that finished them, the finish is undone and they go
  back on course.
* A note is attached to their result so the reason is visible later.

The original lap stays in the record. You're marking it void, not erasing it.

Voiding needs **admin** access.

## Primes

A prime is a mid-race prize for whoever leads on a given lap.

From **More actions → Record prime**:

1. Pick the lap number.
2. Search for the winning rider by bib or name.
3. Give it a label — "Bell lap prime", "Sponsor prime".

Primes are recorded against the race and show up in results and exports, so
whoever's handing out envelopes at the end has a list.

> !!-IMAGE-NEEDED-!! — The Record prime dialog with a lap number and rider selected.

## Relay is different

Relay races also count laps, but they're credited to a team rather than a rider.
