# averageActivePace

The average pace of the user, measured in seconds per meter.

```
var averageActivePace: NSNumber? { get }
```

## Discussion

During regular updates, this property is set to the user’s average active pace since [`startUpdates(from:withHandler:)`](/documentation/CoreMotion/CMPedometer/startUpdates(from:withHandler:)) was called. When you perform historical queries, the property is set to the average active pace between [`startDate`](/documentation/CoreMotion/CMPedometerData/startDate) and [`endDate`](/documentation/CoreMotion/CMPedometerData/endDate).

The property averages the user’s pace only during periods of activity and it omits all periods of inactivity. The value of this property is `nil` when you are performing a query for historical pedometer data and the information is not available (such as when the user did not move between `startDate` and `endDate`). This property is also `nil` for devices that do not support the gathering of pace data.
