Available metrics per Apple Watch workout type

Go to the workout type you want to see the metrics for and tap on the 3 dots in the corner,a list of the available metrics will be shown on that page.

As an example outdoor walking has time,distance and calories burnt and these are the metrics that will be recorded.

There isn't a metric as such,location services is another name for GPS and this is usually on by default.

The sailing workout only measures time and calories burnt so there won't be a metric for distance or speed.

Because Apple hasn't included the ability to measure distance in that particular workout type.
