Changes in the middle of a race

Race day never goes exactly to plan. This page holds the rules for what Trusty Track does when it changes underneath you — a late arrival, a withdrawal, a dead lane, a skipped heat, a wrong time.

One pattern covers the first three. What happens to a round depends on how far it has got:

The round	What happens
Not started	Rebuilt to match the new situation — nothing is at risk, so everybody gets an equal schedule
Part-way through	Every recorded heat is kept. Only the heats still to come change
Finished	Left alone

A late arrival

Add the racer to the roster and check them in. Checking them in is what puts them in the racing — there is nothing else to press.

A round that has not started is rebuilt with them in it.
A round part-way through keeps every recorded heat, and new heats are added at the end so the newcomer gets one turn in each lane — the same spread everybody else got.
A finished round is left alone; they join from the next round.

The added heats need other cars in their lanes, so a few racers run once more than their peers. A timed race shrugs that off; a points race sets that round aside and the Standings page says so. Two children arriving together share their extra heats rather than each pulling in a separate set of veterans.

In a Balanced or Elimination round, a latecomer simply joins the next set of heats — on a clean record in elimination, and never a race that is already decided.
A championship round is never joined directly: a latecomer qualifies for it by racing.
No heats against a checked-in racer on the roster means they arrived after the round they would have been in had finished. They will be in the next round created.

A withdrawal

Open the racer's check-in entry and turn Passed Inspection / Checked In off.

A round that has not started is rebuilt without them.
A round part-way through keeps every recorded heat; their lanes in the remaining heats are emptied. Nobody else's schedule changes, and nothing is set aside — an empty lane gives nobody extra heats.
In Elimination or Balanced, a withdrawal that would leave a still-pending heat with only one car left in it skips that heat instead of running it solo — the same "nobody races alone" rule the format already follows when it draws a fresh set. The survivor is re-fielded in the next set with nothing recorded against them.
A finished round keeps their results.
A championship spot they held in an unraced round goes to the next qualifier.

If it was a mistake, check them back in — they get their place back the same way a latecomer does.

A lane stops working

Settings → Tracks → Lanes in service — untick the lane. It applies the moment you click it, not when you press Save, because a lane dies mid-event rather than by appointment.

Every round generated from then on is scheduled around it: the remaining lanes are used, everybody still races the same number of times, and heats name the lanes that actually exist rather than renumbering them.
A round already under way follows the table above: recorded heats keep their results, and the dead lane is dropped from the heats still to come. The cars that lose a heat this way make the round set aside in a points race.
Tick the lane again when it is fixed and the next round uses it. A track with no working lanes generates no schedule at all, and the settings page says so.

Turning down a track's lane count

Settings → Tracks → Lanes — lowering the number and pressing Save Settings is brought into line the same way a lane going out of service is, following the same table above: a round nobody has raced is rebuilt for the lanes that remain, a round part-way through keeps its recorded heats and has the lane it no longer has dropped from what is still to come (set aside in a points race, same as above), and a finished round is untouched.

Untouched means untouched: a finished round's own results still hold every lane it actually raced. Opening that race's Schedule tab or printing its heat sheet later still shows the lane the track no longer has — labelled not on this track — rather than dropping that lane's result from the page.

Skipping a heat

Skip Heat passes over the current heat without racing it — for when every car in it has scratched.

The schedule moves on. A skipped heat holds nothing up: the round still finishes, and a championship round waiting on it still fills.
It can be raced later with Run if the cars turn up after all.
In a points race its cars are scored as last in it; in a timed race it is simply not part of anyone's average. See Scoring.
In an elimination round a skipped heat is neither a win nor a loss for anyone.

A wrong result

Edit on a recorded heat corrects individual times.
Re-Run clears the whole heat so it can race again — it asks you to confirm first, since it discards every lane's recorded result — and then takes you to the Race tab with that heat ready to arm, the same as Run.
Either way, who advances is re-decided from the corrected results.
If the schedule changes while a heat is armed on the timer — a rebuild, a reorder, a deleted round — the timer disarms itself and says so, rather than recording times against cars that have moved. Re-arm the heat and run it again.
