# runningPower

A quantity sample type that measures the rate of work required for the runner to maintain their speed.

## Declaration

```swift
static let runningPower: HKQuantityTypeIdentifier
```

## Discussion

Discussion These samples use power units (described in HKUnit) and measure discrete values (described in HKQuantityAggregationStyle). During outdoor running workouts, the system automatically records running power samples on Apple Watch SE and Series 6 and later. Sample data may be condensed and/or coalesced by HealthKit. For more information, see Accessing condensed workout samples.
