# HKWorkoutEventType.segment

A constant indicating a period of time of interest during a workout.

## Declaration

```swift
case segment
```

## Discussion

Discussion Use segments to highlight important time periods during a workout. For example, you could use different segments to mark when a runner is going up or downhill. Similarly, when swimming, you can use segments to group consecutive laps with the same style of stroke. Unlike laps, segments can freely overlap.
