## Choose a FIS Knockout bracket

Use the expected number of starters, accounting for racers who may not start, to choose a bracket:

| Expected starters | Bracket |
| ---: | --- |
| 19–30 | 3 rounds, 5 quarter-finals |
| 13–18 | 3 rounds, 3 quarter-finals (unofficial; requires Jury approval) |
| 7–12 | 2 rounds, 2 semi-finals |
| 2–6 | 1 round, 1 final |

## FIS Knockout

The FIS Knockout format is defined by FIS although some changes are made for national competitions. First, FIS now allows athletes to choose their quarter final heats after the qualifier but this is not done at National competitions due to the extra logistics. Secondly, there is not a good solution provided by FIS for categories between 13-18 racers so an unofficial format has been developed to fill this gap. Choosing the correct bracket is simply a numbers game accounting for some racers that are registered but will not start.

**Timed** versus **untimed** describes how lucky losers advance. In an untimed format, the two fastest racers who did not advance by ranking are selected using their qualifier times. In a timed format, they are selected using times from that round. You can use an untimed format while recording heat times, but those heat times will not determine lucky-loser advancement.

### 3 Rounds, 5 Quarter-Finals

-   19 to 30 racers
-   official 5 quarter-final format with 6 racers per heat
-   2 semi-finals with 6 racers per heat
-   A and optional B final with 6 racers per heat

## Ladder

The ladder format is run as an amalgamation of sub-categories that should combine a range of age categories and both genders. This requires the results from final round to be split back into the original categories for awards. An option for the final round is to pull the top racers from each sub-category after the second round into a final for that subcategory.

### 6 Lanes

-   2 to infinite racers
-   3 rounds with an unlimited number of heats per round
-   6 racers per heat

### 4 Lanes

## Old FIS Knockout

The Old FIS Knockout format is defined by FIS but has been mostly replaced with the newer format above. This format has fallen out of favor because the semi-finals and finals only have 4 racers per heat.

### 3 Rounds, 4 Quarter-Finals

-   13 to 24 racers
-   official 4 quarter-final format with 6 racers per heat
-   2 semi-finals with 4 racers per heat
-   A and optional B final with 4 racers per heat
-   consider using FIS Knockout with 3 Rounds and 3 Quarter-Finals instead
