This Friday, a new Activity Challenge will show up in the Activity app on the iPhone for Apple Watch owners in the US. What's it for? Mother's Day, which is Sunday, May 14. Those who earn the special award get a very nice achievement medal and iMessage sticker (shown in the image above).
All it takes to gain the award is to complete a one-mile workout on Sunday, May 14. It doesn't matter if it's a walk, a run or even a wheelchair workout, but you do need to achieve one mile in distance in one workout session.
Record the workout in the Workout app on Apple Watch or any third-party app that integrates with the Apple Health app, and you'll get the special medal and sticker!
