# Age groups and standings groups

**Groups** split standings and start lists by age and gender — for example M40, F30, or youth categories.

**Path (challenge):** Challenge → Settings → **Groups**  
**Path (competition):** Competition → Settings → select a distance → **Groups**

## Club-level group collections

Groups are stored as **collections** at club level. Each collection contains one or more ranges:

| Field | Meaning |
|-------|---------|
| **Title** | Label shown in standings (e.g. M40–49) |
| **From / till year** | Birth years included in the group |
| **Gender** | Male, female, or all |

Create a new collection on the Groups settings page, or pick an existing club collection and attach it to the event.

## Attach groups to an event

### Challenges

One group collection applies to the whole challenge. Standings can filter by group when groups are configured.

### Competitions

Groups are configured **per distance**. A marathon and a 10K can use different collections or share one.

After saving groups while the event is open, DistantRace **recalculates** group assignments and standings in the background.

## Edit or remove groups

- **Save group** — add or update a range inside the active collection
- **Delete group** — remove one range
- **Delete collection** — remove the whole collection from the event (does not delete the club-level template)
- **Delete groups** — detach all groups from the event entirely

::: warning Event ended
Changing groups after an event ends may not recalculate historical standings. Prefer finalizing groups before publishing results.
