How do I get my Apple Watch to track my outdoor walk?

tap the crown

tap workout app

scroll to outdoor walk and tap it

Using Siri has its shortcomings if you have multiple workout apps.

Those settings are on by default, and the questioner would not get Siri to start a workout occasionally if they were not active. The question is one of reliability under the stress of activity. Intermittent failures require thinking outside the box.

I also add a workout "complication" to my morning watch face. Just tap it.
