# Understanding Segments

In race timing, **segments** are the building blocks for measuring and classifying participant performance.

A segment is defined as the time difference between two checkpoints. Segments are used to create rankings, track progress, and provide detailed insights into the race.

Segments are required to generate rankings in **CLASSICAL** races.

## Importance of Segments in CLASSICAL Races

Segments are crucial because they:

* Form the basis for rankings and classifications.
* Provide meaningful comparisons between participants.
* Enable split-time analysis and pacing evaluation.

The most common segment is **Start → Finish**, which represents the total race time. Additional segments (for example, Start → 10k or 10k → Finish) allow deeper performance analysis across the course.

## Segments in Laps / Time-Trial Races

In **Laps / Time-Trial** races, segments are generated automatically as the race progresses.

They are not manually defined as in CLASSICAL races.

## Segments in RUFUS Race Manager

In RUFUS Race Manager, at least one segment must be defined for every CLASSICAL race. Without a segment, rankings cannot be calculated.

Key points:

* **Race Order Segment** → Defines how the main ranking is calculated.
* **Start → Finish segment** → Typically used for overall classification.
* **Gunshot → Finish segment** → Used when no start checkpoint exists.
* **Intermediate segments** → Optional, used for splits and analysis.

### Segment Override

Segment Override allows ranking specific groups using a different segment than the main Race Order Segment.

By default, all participants are ranked using the race’s configured **Race Order Segment**. With Segment Override, selected groups can use an alternative segment for their classification.

Example:

* Race Order Segment: **Chip Time**
* Group: **Elite Men / Elite Women**
* Override Segment: **Gun Time**

In this case:

* General classification is based on **Chip Time**.
* Elite groups are ranked using **Gun Time**.

This is useful when different competition rules apply within the same race, such as elite categories being ranked by gun time while the rest of participants are ranked by chip time.

### Examples of Segments

* **Start → Finish** → Overall classification.
* **Start → Intermediate** → Progress up to a split.
* **Intermediate → Finish** → Performance in the final section.

## Summary

Segments are a core element of race timing:

* Every CLASSICAL race must have at least one segment.
* Segments define how rankings are calculated.
* The Race Order Segment determines the default classification.
* Segment Override allows group-specific ranking rules.
* Additional segments provide deeper performance insights.

Careful segment configuration ensures accurate classifications and flexible ranking logic across different participant groups.
