can I track elevation gain for activities with my apple watch 2?

To show elevation in an outdoor run, open the Apple Watch app on iPhone, tap My Watch, go to Workout > Workout View, then tap Multiple Metric. Tap the workout type, tap Edit, then tap the plus sign next to Elevation. I hope this helps!

As previously advised, Apple Watch Series 2 cannot be used, on a standalone basis, to record elevation gain.

When recording an outdoor workout type via the Workout app on Apple Watch, elevation gain is reported within the workout summary only when the paired iPhone is also taken along during the workout. This applies when the paired iPhone has a barometer (iPhone 6 or iPhone 6 Plus or a newer model).

Elevation doesn’t appear to be a metric available as an option. :(

Hi

Apple Watch cannot be used on a standalone basis to record elevation gain.

When recording an outdoor workout type via the Workout app on Apple Watch, elevation gain is reported within the workout summary when the paired iPhone is also taken along during the workout. This applies when the paired iPhone has a barometer (iPhone 6 or iPhone 6 Plus or a newer model).

The summary has a section called ELEVATION GAIN, but I've noticed that if I ride a route that is pretty much flat, then this will not be shown.

The outdoor cycle will report elevation gain in it's activity summary.
