How to switch Apple Watch Activity distances from km to miles

Open up the Health app on your iPhone

Head to the Walking & Running Distance screen
Click on the “Browse” tab at the bottom, then select “Activity” and then the “Walking & Running Distance” card
Find the options
Scroll to the bottom of this screen, where there is a section named “Options”.
Change the units
At the bottom is one named “Unit”. Click on this, and change from “km” to “mi”.
Check Activity
Head into the Activity app information and you should now find your distances show as miles.
