# Challenge rules and activity limits

**Settings → Rules** (sports activity challenges) defines which workouts count toward results.

## GPS requirement

| Setting | Effect |
|---------|--------|
| GPS required | Only activities with GPS track count |
| GPS optional | Activities with or without GPS |
| No GPS | Non-GPS activities allowed |

Important for virtual-style efforts inside challenges.

## Sync timing

- **Hours after end** — how long after the challenge ends synced activities still count
- **Sync offset** — ignore workouts synced too late after they occurred

## Activity before join

**Count past activities** — include workouts recorded before the participant registered (within challenge dates).

## Per-activity limits

Minimum and maximum:

- Duration
- Distance
- Energy
- Steps

## Daily acceptance

- **Max activities per day** — cap how many count
- **Order** — which activities rank when over the limit (longest, shortest, first synced, etc.)

## Participant troubleshooting

When activities are excluded, participants see reasons on the activity detail page. Share [Why activities are missing](../joining-events/why-activities-are-missing.md).

Organizers can accept individual workouts from **Participants → Workouts**.
